Chapter 6, Problem 6.66P

3.56 Refrigerant-12 in a piston/cylinder arrangement is initially at 50° C, x = 1. It is then expanded in a process so that P = Cv to a pressure of 100 kPa. Find the final temperature and specific volume.

Do not give answer in image and hand writing

Water is put into the boiler at 23oC and 10 bar pressure, where the water will turn into steam saturated at constant pressure. Find of the process and heat required for production 15000 m3 /h slightly under the above conditions. Assume that the velocity of water entering the pot is ignored and steam is known leaves the kettle through a tube with an inner diameter of 0.15 m. The inlet and outlet of the pipe has same height
