his paper analyses the pressure change in centrifugal pump when it is running.The basic computational formula of allowable installing height was derived by using Bernoulli equation. The experimental conditions under which the net suction vacuum Hs is measured are explained and so is the relation between Hs and flow capacity for same type of centrifugal pumps. On the basis if this study,the author turned the basic computational formula into a general one in order to be used in chemical plants for different conditions and transporting different liquids.Finally,the relation between the allowable installing height and net positive suction head is discussed.
