Water is heated in a mixing chamber by mixing it with hot water coming from a heater. The mixing chamber loses heat to the surroundings at a rate of 5 kW. The hot water enters the mixing chamber at a rate of 1 kg/s. The mixed water leaves the chamber fully mixed. - The cold water enters the mixing chamber at 200 kPa and 20°C at a velocity of 3 m/s - The hot water enters at a pressure of 100 kPa and 150°C at a velocity of 2 m/s - The surroundings temperature is 10°C The mixture leaves the chamber at 150 kPa and 70°C at a velocity of 5 m/s. What is the mass flow rate of the cold water and the rate of entropy generation in this process?

A mixing chamber takes in a stream of R134-a at 1 MPa and 12◦C and a second stream at 1MPa and 60 ◦C. The first stream has twice the mass flow of the second; m1 = 2m2 No data is given about the stream 3 exiting the mixing chamber. Therefor, you will need to make two approximations typical for mixing chambers. One is that the pressure changes across the chamber are negligible. You are asked to find the exit temperature...
