A piston/cylinder device contains 0.2 kg water at 1000 kPa, 300o C. There is a constant force on the piston with stops mounted so a minimum volume is 0.025 m3 . It is now cooled to 100o C. Find the final water volume, the work and heat transfer in the overall process and show the process in and T-v diagrams

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
