Steam enters an insulated shell in tube type heat exchanger (operating at steady state) at 7.5kPa with a quality of 95% where it condenses on the outside of the tubes through which cooling water flows. The condensate exits as a saturated liquid at 7.5kpa at 3.5 x 105 kg. The cooling water enters at 15C and exits as a saturated liquid at h 35C . Assuming no pressure drops across the tube or shell (so P-P2, P3=P4), determine the (a) mass flow rate of the cooling water in kg/s (b) the rate of entropy generated for this process kJ S-K (c) Is this device allowed by the second law? ***For a compressed liquid, you may use the following approximations if necessary: VV fer,uur@rh hers Ster S f@T Given Steady state State 1: HO, P = 7.5kPa, x1 = 0.95 State 3: (Cooling water) T3 = 15C Find m CW S State 4: (Cooling water) T = 35C, x4 = 0 State 2: P2 =7.5kPa, x2 =0, m2 = 3.5x105 kg h ,allowed by 2nd law (>0?)
