Steam enters a heat exchanger at 0.1 bar with a quality of 0.95 and exits as a compressed liquid at 0.1 bar and 45°C. Cooling water enters the heat exchanger in a separate stream (no mixing) as a liquid at 20°C and exits as a liquid at 35°C with no change in pressure. Heat transfer from outside of the heat exchanger is negligible, as are changes in PE and KE. Assuming steady state operation, find (a) the ratio of mass flow rate of the cooling water to the mass flow rate of the steam; and (b) the rate of energy transfer from the steam to the cooling water in KJ/kg of steam passing through the heat exchanger.
