You will never be hurt by going to a Further detailed reading is recommended when completing control valve sizing for liquid or even gas flow systems along with consideration of other design factors which should be considered as part of the sizing process such as Liquid Pressure Recovery Factor (F, Note, FluidFlow solves the various forms of the equations described in ISA-75.01.01-2007, taking into account Liquid Pressure Recovery Factor (F. Measuring the flow yields a velocity of 4 ft/min. (Well there are really six, but each colum is shown in Gallons per minute, and then again as Gallons per Hour.) If the Cv is too small for the process, the valve itself or the trim inside the valve will be undersized resulting in the system being starved of the process fluid. This point is called the critical velocity and can be determined by plotting pressure against velocity for various values of mass flow rate (or volumetric flow rate) on a graph. (relative to the lateral) and thus a very small velocity. and Applications. The pipe flow calculation allows you to select from a variety of This size directlyaffects the amount of water that travels through the hose. Streeter, Victor L., E. Benjamin Wylie, and Keith W.
