Step-by-step GuideInfoWorks WS Pro is capable of modelling fire flow.Integral part of water supply modellingUsed during preliminary design to ensure adequate flow and pressureFor firefighting compliance to ensure hydrants can supply enough water and pressure during emergencies.Help model calibration, during which fire flows and residual pressures can be simulated and compared with field data.There are three types of fire flow simulation: Fire Flow Availability, Hydrant Testing, and Forced Fire Flow.The Fire Flow Availability simulation determines the fire flow availability from:required fire flow specificationslocal nodal pressure (calculated as in a normal run)assumed hydrant characteristics.It then checks the ability of each hydrant in turn to meet the defined fire flow requirements. Each hydrant is considered independently, as if no other hydrant in the system is open.Fire Flow Availability results are calculated using the orifice equation. These results can be used to show the ability of individual hydrants to sustain additional levels of demand for firefighting or other similar purposes.Note: Fire flow is not applied to the network; therefore, the effect of increased flows on the network is not considered.Note: You may need to carry out more than one fire flow availability simulation in order to analyze and check that availability reaches the required standard throughout the network.Fire Flow Availability simulation results include:FFA Flow – the maintained fire flowFFA Residual Pressure – the residual pressure after the fire flow is considered.These additional results can be viewed via the Node Results Grid, as well as in individual node graphs and grids. Omni's PSI to GPM calculator allows you to determine water's flow rate in GPM from the PSI reading of a pressure gauge. You can also use this calculator to convert PSI to gallons per hour.Continue reading this article to learn:The difference between PSI and GPM.What is Bernoulli's equation?How to calculate GPM from PSI and pipe size?PSI and GPMPSI or pounds per square inch is a unit of pressure. We can define 1 psi as the pressure due to a force of one pound-force applied on an area of one square inch. Thus, a more accurate term for psi would be pound-force per square inch (lbf/in2).One psi is approximately equal to 6894.76 pascals (the SI unit of pressure is pascal or Pa). It is very commonly used in measuring pressure in industries and everyday life, for example, tire pressure, fire hydrant pressure, etc.GPM or gallons per minute is a unit of flow rate, i.e., it specifies how fast a liquid (for example, water) moves through a pipe or pump. One US gallon per minute is approximately equal to 6.309×10−5 m3/s6.309 × 10^{-5}\ \rm{m^3/s}.Since PSI is a measure of pressure and GPM is a measure of flow rate, we can not directly convert one into another. However, we can use Bernoulli's equation for an incompressible fluid to calculate the flow rate in GPM if certain other variables are known.Before going further, let us first try to understand what Bernoulli's equation is.What is Bernoulli's equation?Bernoulli's equation states that for an incompressible, frictionless fluid, the sum of pressure (PP), kinetic energy density, and potential energy density is constant, i.e.:P+12ρv2+ρgh=constant\scriptsizeP + \frac{1}{2} \rho v^2 + \rho g h = \text{constant}where:ρρ — Density of the fluid;vv — Velocity of the fluid flow;hh — Height from the ground; andgg — Acceleration due to gravity.The potential energy density is calculated with the use of a modified potential energy equation, with density instead of mass of the fluid.When the fluid flows through a pipe that has varying diameter and height, the pressure and energy densities at two locations along the pipe are related as:P1+12ρv12+ρgh1=P2+12ρv22+ρgh2\scriptsizeP_1 + \frac{1}{2} \rho v_1^2 + \rho g h_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g h_2A typical geometry used for the derivation of Bernoulli's equation. (Source: wikimedia.org).For a fluid flowing at a constant depth/height, the above equation changes to:P1+12ρv12=P2+12ρv22\scriptsizeP_1 + \frac{1}{2} \rho v_1^2 = P_2 + \frac{1}{2} \rho v_2^2 In other words, as

Not hook up to the water supply for daily use. I use my pump so that the water in my tank is regularly being used and replaced. It is not sitting unused, so microorganisms have little time to develop. When you drain your tank to put it in storage, the fresh water tank is drained by a ball valve near and below the fresh water tank, probably tucked in the corner of a storage compartment. The drain valve should be closed when done, lest insects and small critters crawl into your tank. There are mixed opinions regarding the use of a filter when filling your water tank. Many use filters, typically when in a campsite that has a water hydrant. The filter will slow the flow rate significantly, making filling the tank a slow process. Conventional filters will do a good job of removing any sediment or particulate materials, and some can remove some dissolved materials such as chlorine. They will not remove microorganisms or heavy metals, nor can they make hard water soft. To remove microorganisms, you need a filter with a pore size of 0.2 microns or smaller. The flow rate will be VERY slow. I do not use a filter and have never had a problem, but that might change with my next fill. (I choose not to use a filter because I usually do not have a hydrant at my site and using a filter really slows the fill time.) I have heard of others not. Hydrant Flow Calculator.

Last Updated on March 10, 2023 by You still have to park 15 feet away.Fire hydrant tickets will cost you $115Fire hydrant tickets are expensive and avoidable. I urge you to formulate a fire hydrant parking strategy and adhere to it, especially since they’re more than 109,800 fire hydrants in the five boroughs to dodge artfully.Here’s where it all started:New York City’s first fire hydrant was installed in 1808 at the corner of William and Liberty Streets, this hydrant was most likely a wood case hydrant. By 1817, the first regular iron hydrants were being installed throughout the city.”I’ve had great success beating fire hydrant parking tickets, but it’s not easy. Here is some helpful information that will save you $115Formulate a fire hydrant parking strategyFire hydrants are ubiquitous throughout our fair city, and there is hardly a block without one. How do you know whether your valuable parking space is within 15 feet of a hydrant? Walk off the distance? Or rely on the parking g-ds for protection? Do you guess?Joe keeps a tape measure in his glove compartment. Sue holds a 15-foot cord in her car (with enough extra line to loop onto a fire hydrant).Our beautiful friends measure the distance between their car and a fire hydrant each time they park near one. Does this take a little extra time? Sure. But, time spent is a fire hydrant parking ticket avoided.NYC Council joins the conversationIn 2010, Council Members David Greenfield (D-Brooklyn) and Daniel Dromm (D-Queens) offered proposals to help the N.Y.C. driving public.Greenfield proposed legislation that required painting curbs red adjacent to fire hydrants. Dromm proposed legislation that reduced the no-parking zone from 15 feet to 10 feet on all sides of a fire hydrant.A spokesperson for the N.Y.F.D. disagreed with the proposal reducing the no-fly zone from 15 to 10 feet but supported the proposed red curb painting:…Fire engines need 30 feet to connect as fast as possible. As for the red curbs, the spokesman said it would be helpful.”Yet, neither of these bills saw the light of day.On January 22, 2015, Council Member Gentile introduced A new law. The new law would require the curbs adjacent to fire hydrants, and bus stops to be painted red. Here’s the full text of the bill:By Council Members Gentile, Williams, Koo and LancmanA Local Law to amend the administrative code of the city of New York, in relation to the curbs adjacent to a fire hydrant or bus stop.Be it enacted by the Council as follows:Section 1. Title 19 of the administrative code of the city of New York is amended by adding a new section 19-175.4 as follows:§ 19-175.4 Curbs adjacent to fire hydrants and bus stops. a. Notwithstanding any other law, rule or regulation, any curb adjacent to a fire hydrant located on a public sidewalk or a bus stop shall be painted the color red. Such curb shall be painted the distance by which a motor vehicle is prohibited from stopping, standing or parking on either side of a fire hydrant or bus stop. For purposes of this section, the term “bus stop” shall mean a location designated by signage for vehicles under the jurisdiction of the metropolitan transit authority to pick up or discharge passengers.§ 2. This local law shall take effect 90 days after its enactment into law.”When you’re right-FIGHT! What if I still get a fire hydrant ticket?Here are some tips:Don’t be the last car in the line closest to the fire hydrant. You are significantly increasing your chance of a parking ticket.Prepare your defense before leaving the parking space. Take photographs showing your cord or tape measure extended beyond 15 feet from the fire hydrant.Make sure you take extra photographs proving the pictures were taken at the location the parking ticket was issued (place of occurrence)Fight your parking ticket online.Prepare a defense certification that not only certifies your testimony but also certifies your exhibits. Prepare exhibits that tell your story in an organized, understandable fashion. Use captions to enhance the power of your exhibits.

Look through our Flow Controls to find the right fit for you.How to use the Orifice Flow CalculatorThis Air flow calculator is based on the flow through an orifice in a common application where an orifice restrictor is supplied via a regulated pressure supply and vents to atmosphere. The Upstream pressure (PU) is gauge pressure that is set in the system. The downstream pressure (PD) is set to absolute pressure and used for the pressure differential and mass flow rate calculations.Users will typically select an upstream gauge pressure and orifice size to determine the flow rate. Other orifice restrictor applications may require users to overwrite values in the calculator such as PD, but pay attention to the units specified.*Results of this calculator will produce nominal values. Real world values may vary per application. If you are designing a product, we recommend using Air Logic’s Free Sample Program to test in your application. How to Calculate Volume Flow rateThis orifice flow calculator uses the following equation to calculate the volumetric flow rate:NFPA flow coefficient for Fahrenheit and Psi (pressure per square inch) is used to calculate CFM (cubic feet per minute). Other units are available in the calculator and are converted outside of this base equation.Definition of terms:Q = Air Flow in CFMΔP = Pressure Drop across orificePD = Pressure DownstreamG = Specific Gravity of the gas/air (Air = 1)TU = Upstream TemperatureCv = Flow Coefficient How to Calculate Mass Flow RateBy using a STP (standard temperature and pressure (PD)) in this calculator, a small “s” will appear in front of the flow units. The “s” stands for “standard” and indicates the output (in volumetric flow rate) may be used to calculate the mass flow rate.To calculate the mass flow rate, multiply the density of the gas (at matching STP conditions) by the volumetric flow rate..

Calculate the required flow coefficient Cv/Kv for the flow rate and pressure drop. For a specific control valve, flow coefficient Cv/Kv is determined experimentally by control valve manufacturers, and you can found it in manufacturers technical specifications. They express coefficient Cv/Kv as the flow rate of water in g.p.m. [m3/h] for a pressure drop of 1 psi [1 bar] across a flow passage [flow coefficient: Cv-imperial, Kv-metric]. You can use the calculator to calculate maximum flow rate through control valve for given pressure drop and known flow coefficient of control valve Cv. With maximum flow rate calculated, you can compare control valves from different manufacturers for their efficiency for the same nominal size. Control valve calculator is suitable for turbulent flow of liquids. When is this calculator not relevant? Flashing, cavitation, and chocked flow may reduce the control valve capacity. That calculation is not in this version of control valve calculator. How is the calculation executed? The calculator is calculating flow coefficient Cv/Kv using the relationship between pressure drop and flow rate in the control valve which is for complete turbulent flow following power law where flow coefficient Cv/Kv is the proportional constant: where is: q - flow rate Cv - flow coefficient Δp - pressure drop S - specific gravity (relative density) Available in download version save/open multiple resultsexport to Word and Excelprint resultscreate list of custom fluid propertiesresistance factor K for flow in valves and fittingspipe surface roughness selectionpipe material selectionselect between gauge and absolute pressurecompressible isothermal flowdry
