p = pressure (kg/cm2) Example - Converting Pump Head - feet - to Pressure - psi The pressure - psi - of a water pump operating with head 120 ft can be calculated with eq. 1 as: p = 0.433 (120 ft) (1) = 52 psi Example - Converting Pressure - psi - to Pump Head - feet...
Convert pound/square inch [gauge] to foot of headpsig foot of head The above form works if you are measuring differential pressure, such as the difference in psi between two points. If you are measuring relative to vacuum and want to resolve the pressure relative to the atmosphere, then ...
Convert from Pressure - Pounds per Square Inch (psi) to Head of Water in Feet (fth2o) Convert from Head - Water Feet to Pressure in Pounds per Square Inch 1 ftH2O = 0.4335 psi = 62.43 lbs/ft2 1 psi (lb/in2) = 144 psf (lbf/ft2) = 6894.8 Pa (N/m2) = 6.895x10-3 N/mm2 =...
We can convert pressure to head p (psi) =SG x h (feet) / 2.31Therefore Ef = SG x Hf / 2.31 x A x dSG x A x D /2.31 is equal to weight, therefore Hf is energy per unit weight as expected. Hf is the friction head which we can find form tables or other methods. ...
Static pressure head represents the energy contained in the liquid due to its pressure. The pressure head has dimensions of length and is calculated in units of feet or meters. 6.9.1.2 Velocity head Velocity head represents the kinetic energy contained in the liquid due to its velocity. This ...
using the formula: NPSHr = ATM + Pgs + Hv – Hvp, where ATM is atmospheric pressure, Pgs is the suction pressure gauge reading taken at the pump centerline and converted into feet of head, Hv is the velocity head, and Hvp is the vapor pressure of the fluid expressed in feet of head...
a. the height of the surface of liquid above a specific point, esp when considered or used as a measure of the pressure at that point: a head of four feet. b. pressure of water, caused by height or velocity, measured in terms of a vertical column of water c. any pressure: a hea...
difference between the discharge point and the pump. Pump head describes pressure in terms of distance, usually in feet or meters. Pressure can be converted between units of distance and units of force per unit area: 2.31 ft of head equals 1 psi (pound per square inch) of pressure. ...
Figure 1 Measuring pressure with a pressure gauge. You read 60 psi on the gauge of the pump in your house and you know everything is fine, everything should work properly. So what is it about head? Why do people even talk about it, and what does it have to do with pressure?
