A model pump (Fig. P12.32) delivers 80°C water at a speed of 2400 rpm. It begins to cavitate when the inlet pressure p_i= 83 kPa absolute and inlet velocity V_i 6 m/s.

(a) Compute the NPSH of the model pump. Neglect losses and elevation changes between the inlet section where p_i is recorded and the cavitation region in the pump.

(b) What is the required NPSH of a prototype pump that is four times larger and runs at 1000 rpm?
