Flow rating
WebCFM (Cubic Feet per Minute) is the imperial method of describing the volume flow rate of compressed air. It must be defined further to take account of pressure, temperature and relative humidity - see below. ICFM. ICFM (Inlet CFM) rating is used to measure air flow in CFM (ft 3 /min) as it enters the air compressor intake . ACFM WebThe flow rate value can be determined using a formula; the larger the value, the higher the flow rate will be through the valve at a given pressure drop. Flow rate is expressed as Cv or Kv, depending on the system of measurement being used (imperial or metric, respectively). The minimum required Cv value is often listed in a valve’s product ...

WebThe Equations. This flow calculator uses the Hazen Williams equation to solve for flow assuming that the pressure at the outlet is zero (open to atmosphere) and thus the entire pressure at the hose bib is dissipated by friction losses in the hose. The pressure at the hose bib is assumed to be the dynamic pressure (while water is flowing) not ... 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
