Q1/ A stream of warm water is produced in a steady flow mixing process by combining 1.0 kg/s of cool water at 25 °C with 0.8 kg/s of hot water at 75 °C. During mixing, heat is lost to the surroundings at the rate of 30 kJ/s. What is the temperature of the warm water stream? Assume the specific heat of water constant at 4,18 kJ/kg K

Box the final answer. Write legibly. Steam flows into a turbine at a rate of 3.5 kg/s and ¾ MW of heat are lost from the turbine. Ignoring elevation and kinetic energy effects, calculate the power output from the turbine in KW? Steam pressure entering the turbine is 62 Bar at 440ºC and leaves at 74 Kpa.
