Write the turbine specific speed in terms of the flow

coefficient and the head coefficient.

 Data measured during tests of a centrifugal pump

driven at 3000 rpm are

The flow rate is 65 gpm and the torque applied to the pump

shaft is 4.75 lbfft. The pump efficiency is 75 percent, and the

electric motor efficiency is 85 percent. Find the electric

power required, and the gage pressure at section 2 .
