An insulated heat exchanger is used to heat the domestic hot water supply using twoseparate streams of hot water supplied from two different solar collectors. The two hotwater supply temperatures from the collectors are 80oC and 50oC. The flow configurationand mass flow rates are shown below. The domestic hot water is heated from 10oC to55oC. What is the exit temperature of the solar collector water?2. Steam enters a turbine at 3MPa and 500oC at a rate of 6kg/s and a velocity of 150m/s andan elevation of 2m. The steam exits at 0.3MPa, 150oC, 80m/s, and 0.5m. The steam islosing heat to the surroundings at a rate of 300kW. Determine the power output of theturbine.
Nothing is shown below, and not clear if the two solar collectors work separately .
