A pump delivers water at a steady rate of 1136 L/min. At the upstream of the pump (inlet), the pipe diameter is 9 cm and the pressure is 124 kPa. At the downstream of the pump (outlet), the pipe diameter is 2.5 cm and the pressure is 414 kPa. The change in water elevation is across the pump is zero. If the water temperature rises from room temperature (~24 ̊C) to 32 ̊C,

calculate the electric power input required for the pump if the pump is working with 100% electromechanical efficiency.
