The figure below shows a pump delivering 0.014 m3/s of crude oil (SG = 0.85) from an underground storage drum to the first stage of a processing system. (a) If the total energy loss in the system is , calculate the power added by the pump in kW. (b) If the power input to the pump is 16.5 kW, what is the mechanical efficiency of the pump?

1) A pelton wheel is used to produce hydroelectric power. The average radius of the wheel is 1.83 m, and the jet velocity is 100 m/s from a nozzle of exit diameter equal to 10 cm. What is the volume flow rate through the turbine in m3/s? a) 263.02 b) 0.801 c) 78.54 d) 0.785 2) A water pump increases the pressure of the water passing through it (see picture below). The flow is assumed to be incompressible. If the outlet diameter is less than inlet diameter, which of the following about outlet and inlet fluid velocity is correct? a) Vout < Vin b) Vout > Vin c) Vout = Vin d) cannot be determined
