Steam at a pressure of 008 bar and a quality of 932 enters

Question

Steam at a pressure of 0.08 bar and a quality of 93.2% enters a shell-and-tube heat exchanger where it condenses on the outside of tubes through which cooling water flows, exiting as saturated liquid at 0.08 bar. The mass flow rate of the condensing steam is 3.4 x 10^5 kg/h. Cooling water enters the tubes at 15⁰C and exits at 35⁰C with negligible change in pressure. Neglecting stray heat transfer and ignoring kinetic and potential energy effects, determine the rate of entropy production in kW/K for steady-state operation

Note: Mass Flow Rate of cooling water is 9.1 x 10^6 kg/hr
