| Abstract: | The formula to calculate installing height of centrifugal pump is derived from permissible vacuum suction height H s or net pump suction head Δh based on basic principles.Consistency of the two methods is proved in theory.Also pointed out are mistakes found in materials as that units of variables in formula do not unite and the saturation vapor pressure of water at 20 ℃ is confused with the saturation vapor pressure of liquid transported. |
