Water flows through two adiabatic turbines and a heat exchanger as shown in the picture. Hot air is used to provide additional energy to the water between the two turbines. The first turbine has a power output of 8,000 kW. Determine the power output of the second turbine in kW and the process efficiency of each turbine. Determine the state of steam in turbine 1, Formulate the 1st Law for turbine 1, and solve for the flow rate of steam. Formulate the 1st Law for the heat exchanger, and solve for the temperature at exit
