5.61 If viscosity is neglected, typical pump-flow results are shown in Fig. P5.61 for a model pump tested in water. The pressure rise decreases and the power required increases with the dimensionless flow coef-ficient. Curve-fit expressions are given for the data. Suppose a similar pump of 12-cm diameter is built to move gasoline at 20°C and a flow rate of 25 m³/h. If the pump rotation speed is 30 r/s, find (a) the pressure rise and (b) the power required.
