A. When sizing for continuous flow rate, subtract the pressure drop at the operating gpm flow across the softener from line pressure. At least a 30 psi should be left for working pressure. B. When sizing for peak flow rate, subtract the pressure drop across the softener from line pressure.At least a 20 psi should be left for working pressure.

Flow Calculation for Gases The coefficient of flow (Cv) is a formula which is used to determine a valve’s flows under various conditions and to select the correct valve for a flow application. The Cv was designed for use with liquid flows, it expresses the flow in gallons per minute of 60º F water with a pressure drop across the valve of 1 psi.

To obtain values for flow rate A and B, we must take into account the molar ratio between B and A and the concentration of solutions A and B (c A and c B). These are related as in Equation 3, since by multiplying the concentration (mmol/mL _) by the flow rate (mL/min _) we get a measure of the amount of substance per unit time (mmol/min _). For ...

Calculating Nozzle Flow Rate - Physics Forums
Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time. To do this we work out the area of the nozzle and then multiply it by the velocity of the water coming from the nozzle to give us volume per unit of time. So nozzle flow rate is just area of the outlet ...
