Extracted text: Question 3 Liquid water at 100 kPa and 25°C is heated in a chamber by mixing it with superheated steam at 100 kPa and 300°C. Liquid water enters the mixing chamber at a rate of 3.4 kg/s, and the chamber is estimated to lose heat to the surrounding air at 25°C at a rate of 2100 kJ/min. If the mixture leaves the mixing chamber at 100 kPa and 75°C, determine (a) the mass flow rate of the superheated steam, (b) the exergy destruction during this mixing process, (c) the exergy recovered during this mixing process and (d) the second-law efficiency of the mixing chamber. 2100 kJ/min 25°C 3.4 kg/s Mixing chamber 75°C 100 kPa 300°C
