11.35 kg/s of saturated liquid water enters a boiler at 20C. 3 kg/s seeps out (exits) the boiler at 95C with quality of 40%. The remainder exits as steam (superheated water vapor) at 350C, 500 kPa, through a pipe that is 35 meters higher than the inlet pipe, with a velocity of 120 m/s. The surroundings are constant at 377C. [16] (a) Calculate the heat transfer rate (in kJ/s) for this boiler. [17] (b) Calculate the rate of entropy generation for this boiler (in kJ/K-s or kW/K).
