What is the effect of density of the liquid on the performance of the Pump?
A. Pressure developed and power consumed by the Pump is directly proportional to the density of the liquid. This is explained as under. If a Pump develops 1kg / cm2 pressure and consumes 1 Kw power for a density of 1 g / cm3 the pressure developed by the Pump for another liquid of a density of 1.5g / cm2 and power consumed will be 1.5 Kw.
