head units - like lb/in 2, atm, inches mercury, bars, Pa and more. Pressure Units - Online Converter - Convert between pressure units like Pa, bar, atmosphere, pound square feet, psi and more.Pipe and Duct Systems - Total Head Loss - Major and minor loss in pipes, tubes and duct systems.Centrifugal Pumps - Stable and Unstable Flow - The characteristics of stable and unstable flow.Centrifugal Pumps - Capacity Modulation - Modulating pumps to adapt capacities to variable process demands.Centrifugal Pumps - An introduction to Centrifugal Pumps.Pumps - Piping systems and pumps - centrifugal pumps, displacement pumps - cavitation, viscosity, head and pressure, power consumption and more.It can be simpler to discuss the performance pumps in terms of head rather than pressure since the use of head makes the pump curve applicable to any liquid regardless of density. Identical pumps will develop the same head when running at the same speed but the discharge pressure is quite different due to the different densities of the liquids. Pressure when handling Liquids of different Density Liquid

Feet of Head Water to psi Headĭownload pressure vs head imperial units as pdf fileĭownload water pressure vs head - SI units as pdf file Head vs. The head in feet water column can be calculated from pressure 100 psi with eq. = 52 psi Example - Converting Pressure - psi - to Pump Head - feet The pressure - psi - of a water pump operating with head 120 ft can be calculated with eq. P = pressure (kg/cm 2) Example - Converting Pump Head - feet - to Pressure - psi P = pressure (bar) Converting pressure in kg/cm 2to head in metre P = pressure (psi) Converting pressure in bar to head in metre Converting pressure in psi to head in feet Since pressure gauges often are calibrated in pressure - psi or bar - a conversion to the heads commonly used in pump curves - like f eet or meter - may be required. P = pressure ( kg/cm 2 ) Converting Pressure to Head Pumps characteristic curves in metre of head can be converted to pressure - kg/cm 2- by the expression: P = pressure (bar) Converting head in metre to pressure in kg/cm 2 Pumps characteristic curves in metre of head can be converted to pressure - bar - by the expression: SG = specific gravity of the fluid Converting head in metre to pressure in bar Pumps characteristic curves in feet of head can be converted to pressure - psi - by the expression: Converting Head to Pressure Converting head in feet to pressure in psi Pumps characteristic curves are often in head - feet or metres - and a conversion to pressure scales commonly used in pressure gauges - like psi or bar - may be required.
