Water at 20 0C is pumped at a rate of Q4= 0.022 m3/s from lower reservoir to a higher reservoir with a height difference of H4=43 m as shown in the figure. The flow is assumed steady and incompressible. If irreversible losses in the pipe can be neglected, calculate the pump efficiency in percent, if the electric motor is rated at P4=29.4 kW and the motor efficiency can be assumed to be n4=82%.
