'2. 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 10s kg/h Cooling water enters the tubes at 15 %€ and exits at 35 *€ with negligible change in pressure. Neglecting stray heat transfer and ignoring kinetic and potential energy effects, determine the mass flow rate of the cooling water; in kg/h; for steady-state operation.'
