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?

An industrial facility needs a flow of 100 gpm of hot water at 180°F, 50 psia. Two designs are being considered to make the hot water. In Design 1, the hot water is produced by injecting steam into an insulated mixing chamber through which the water passes. The water enters the chamber at 50°F, 50 psia. Steam is injected into the chamber at 325°F, 50 psia. The hot water leaves at the required flow rate and temperature. For this system...
