Webhead. 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 equation [1] where SG is the specific gravity of the fluid. Figure 1 The pressure variation WebTo determine the pressure generated by a 40 feet of Diesel, you will need to know the specific gravity (S.G.). The S.G. of Diesel varies depending on temperature and diesel type, but 0.95 is the maximum often indicated by …
Since pressure gauges often are calibrated in pressure - psi or bar - a conversion to the heads commonly used in pump curves - like feet or meter - may be required. See more The head in feet water column can be calculated from pressure 100 psi with eq. 3 as: Where specific gravity of water = 1. See more 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. It can be simpler to discuss the performance pumps … See more WebSep 11, 2024 · Available NPSH = (P1 – Pv) 2.31 Specific Gravity + Z1 – Hfs.
