Ejector Theory

NPSH (net positive suction head) = (pressure head of source) + (static suction head) - (friction head of the suction line) - (vapor pressure of the flowing liquid). [Pg.166]

Hydraulic horsepower is obtained by multiplying the weight rate of flow by the head difference across the pump and converting to horepower. For example, HHP = (gpm)(psi)/1714 = (gpm)(sp gr)(ft)/3960. [Pg.166]

Brake horsepower is the driver power output needed to operate the pump. BHP = HHP/(pump efficiency). [Pg.167]

Driver horsepower, HP = BHP/(driver efficiency) = HHP/(pump efficiency)(driver efficiency). [Pg.167]

Axial flow is flow developed by axial thrust of a propeller blade, practically limited to heads under 50 ft or so. [Pg.167]

Centrifugal pump consists of a rotor (impeller) in a casing in which a liquid is given a high velocity head that is largely converted to pressure head by the time the liquid reaches the outlet. [Pg.167]
