ABSTRACT
Fluid impedance of load~ ZL(D) ~ ~~ (D) ( 5-19) The pump leakage resistance R 11 can be found by lab testing of an existing pump. As soon as the hydraulic load is specified in detail, Eq. ( 5-I 9) can be made specific. For example, if the load were simply a flow resistance RL, we would have RL = D.p/QL.
