An oil pump is powered by a 5kW electric motor. The pressure at the outlet and the inlet of the pump at full load is measured to be 450 kPa and 200kPa, respectively. If the oil flow rate through the pump is 18L/s and the changes in elevation and the flow velocity across the pump are negligible. Determine 1) the energy flow rate of the oil at the inlet; 2) the difference of energy flow rate between the outlet and inlet; 3) the overall efficiency of the motor-pump system? To generate electricity, a hydraulic turbine-generator system is installed at a lake location where the depth of the water is 50 m. Neglecting the kinetic and flow energy, if water is to be supplied at a rate of 5000 kg/s, the shaft power generated is measured to be 2000 kW, and the overall efficiency is 75 percent, determine (a) the mechanical efficiency of the turbine; (b) the electrical efficiency of the generator; (c) the electrical power generated; (d) the electrical current if the output voltage of the generator is 1200V; (e) the shaft rotation rate (in rpm) if the torque is 20N.m.
