If you already have a pump installed in one of your buildings, then you should have a checklist or a sheet that comes which is the datasheet for that pump. All too often, parts of this design data are missing and that's frustrating. But if you have some data missing then we're ... Webof the system). z is the elevation, v the velocity of fluid particles and H the pressure head. H 1 and H 2 represent the pressure heads corresponding to the pressures in the tanks p 1 and p 2. If the tanks are open to atmosphere that H 1 and H 2 will equal zero. It is always possible to calculate pressure head when the pressure is known using

WebAug 24, 2024 · H H is the pressure head in meters; \rho ρ is the fluid's density in kilograms per cubic meter; and g g is the gravitational acceleration in meters per second squared. From the formula above, we can see that the discharge and hydraulic head are both directly proportional to the hydraulic power. Weband the density of the fluid; i.e. p(psi) = dens. (lbf/ft3) x h(ft)/144 or in terms of specific gravity SG, p(psi) = SG x h(ft)/144/62.34. On the right we see a pump pushing water upwards as far up as it can, this is known as the shut-off head of the pump, and this condition occurs at zero flow. same head that the water tank produces. ten thirty one
