Water is heated in an insulated, constant-diameter tube by a 7.7-kW electric resistance heater. If the water enters the heater steadily at 20°C and leaves at 75°C, determine the mass flow rate of water. The specific heat of water at room temperature is c = 4.18 kJ/kg·°C. The mass flow rate of water is kg/s.
