Flow rating
WebGPM stands for gallons per minute and is a measurement of how many gallons a pump can move per minute. It is also referred to as flow rate. GPM is variable based on another measurement known as the Head, which refers to the height the water must reach to get pumped through the system. It is also referred to as flow rate. WebJan 8, 2015 · However, discharges with two-inch valves do not count in rating a fire pump. NFPA 1901 rates fire pumps by adding the total rated capacity of each discharge. Sentence 16.7.1 says, “Discharge outlets of 2½-in. (65 mm) or larger shall be provided to discharge the rated capacity of the pump at the flow rates shown in Table 16.7.1.”

WebThe Cv tells you how to properly size your valve so it has minimal effect on the hydraulic efficiency you’ve engineered into your system. It is a number published by the valve manufacturer that describes the number of U.S. gallons that can pass through a valve (in a fully open position) at a pressure drop of 1 PSI. WebExample of Pressure Loss Determination by Cv Rating On a certain valve a Cv rating of 19.2 is published for water flow. Find the pressure drop through this valve on a 15 GPM flow of 200 SSU hydraulic oil. First, convert the Cv from water to 200 SSU viscosity.· Table 2 shows a correction factor of 38. 19.2 ÷ 38 = 0.505
The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where: … See more The metric equivalent flow factor (Kv) is calculated using metric units : where Kv is the flow factor (expressed in m ·h ).

WebMay 28, 2024 · The value in the loss column provides the friction loss factor at a given flow rate. To calculate friction loss, divide the total length of pipe by 100 and multiply it by the friction loss factor. For example, 40 gpm through 290 feet of 2-inch pipe will result in a friction loss of 7.7 feet of water (290÷100*2.64).
