Flow rating
WebDFU (Drainage Fixture Unit Values) is defined by the the Uniform Plumbing Code (UPC) and can be used to determine required drainage capacities from fixtures and their service systems. A Fixture Unit is not a flow rate unit but a design factor based on the rate of discharge, time of operation and frequency of use of a fixture. WebImportance of proper valve sizing. The flow coefficient of a control valve ( C v) is a numerical value expressing the number of gallons per minute flow of water the valve will pass with a constant pressure drop of 1 PSI from …

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 WebFig. 1: Basic calculation for CV, where Q is the rate of flow (gallons per minute), SG is the specific gravity of the fluid, and P is the pressure drop across the valve (psi). Because air is compressible, CV must have additional factors built into the equations to compensate for that compressibility. For pneumatic applications, CV should be ...
