A pump delivers fluid at the rate of 90 kg/min. At the inlet to the pump, the specific enthalpy of the fluid is 46 kJ/kg, and at the outlet from the pump the specific enthalpy of the fluid is 175 kJ/kg. If 105 kJ/min of heat energy is lost to the surroundings by the pump, determine the power required to drive the pump if the efficiency of the drive is 90 %.
