How do you find the coefficient of a valve?

How do you find the coefficient of a valve?

Q*sqrt(SG/(P1-P2)) Cv is the Flow Coefficient which describes how much fluid will flow (GPM) through the valve for a given pressure drop of 1 psi. Q is the Flow Rate (GPM). P1 is the Upstream Pressure (psi). P2 is the Downstream Pressure (psi).

What is the unit of gas flow rate?

What is Gas Mass Flow Rate? Gas mass flow rate is the actual mass of a gas which moves through a measurement instrument per unit of time. Its units are usually in standard liters per minute (slpm) or standard cubic centimeters per minute (sccm) in SI units.

What is unit of flow?

Flow, or volumetric flow rate, is simply the volume of fluid that passes per unit of time. In water resources, flow is often measured in units of cubic feet per second (cfs), cubic meters per second (cms), gallons per minute (gpm), millions of gallons per day (MGD), or other various units.

How is flow rate and water pressure measured?

Take the amount of water in the jug in litres (e.g. 0.8 litres) and multiply this by 10. This will give you your flow rate in litres per minute (e.g. 0.8 litres x 10 = 8 litres per minute). If your flow rate is less than 10 litres per minute, you may have what is considered low water pressure.
