T B A D Consider the cycle in the diagram (very similar to the Rankine Cycle) using water as the working fluid. Process A-B: A saturated mixture of water is pumped from low pressure to a high pressure saturated liquid in an iso-entropic (and adiabatic) process. Process B-C: The high pressure saturated liquid enters a boiler where it is heated at constant pressure process by an external heat source to a super-heated vapor. Process C-D: The super-heated vapor goes through a turbine, generating power exiting as a saturated vapor.

2. An electrical power plant that uses the Rankine cycle has a pump to increase the water pressure and multiply it by 50. In addition, there is a boiler whose fuel has a calorific value of 35 MJ/kg. The water that enters the process has a temperature of 60 °C and is at atmospheric pressure. The steam that leaves the turbine has a quality of 70% and the work generated in the turbine is 300 MW. a. How much water is needed to run the plant? b. What is its efficiency?
power plant has steam entering at 70 bar, 450°C into HP turbine. Steam is extracted at 30 bar and reheated up to 400°C before being expanded in LP turbine upto 0.075 bar. Some portion of steam is bled out during expansion in LP turbine so as to yield saturated liquid at 140°C at the exit of open feed water heater. Considering HP and LP turbine efficiencies of 80% and 85% determine the cycle efficiency. Also give layout and T-s diagram.
