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, asHydrant Flow Test Calculator - TCESD12permits.com

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 notHydrant Flow Test Calculator - Rotaflow
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.Hydrant Flow Test Calculator - HaysCountyPermits.com
