Problems 2022 are based on the following statement: Siaturated liquid ammonia at 10C is partially vaporized through a let-down valve to provide a vaporizer as saturated 20. (4 pts) The amount of heat that can be removed by the refrigeration system at 10=C is [A] 6,020 kW [B] 6,125kW [C] 6,483kW [D] 6,515kW 21. (4 pts) The power required to compress the saturated ammonia vapor leaving the vaporiter to th higher pressure is (A) 99kW (8) 396kW [C) 495kW (D) 1303kW 22. (4 pts) Calculate the coefficient of performance (COP) of the refrigeration system. 23. (4 pts) Which of the following statements regarding the utility system is/are correct? (ii) In a steam cycle, steam is produced in a boller and passed through a turbine to gener power, and the turbine outlet is cooled down and pumped back to the boller.
