Consider a steam power plant that operates on a simple ideal Rankine cycle and has a net power output of 45MW. Steam enters the turbine at 7 MPa and 500 ˚C and is cooled in the condenser at a pressure of 10kPa by running cooling water from a lake through the tubes of the condenser at a rate of 2000 kg/s. Show the schematic diagram of the power plant and draw the cycle on a T-s diagram with respect to saturation lines. Also, determine (a) the thermal efficiency of the cycle, (b) the mass flow rate of the steam, and (c) the rise in temperature of the cooling water. Repeat your calculations assuming an isentropic efficiency of 85 and 90 for the turbine and the pump, respectively.
The first steam power plant operates on an ideal reheat Rankine cycle. Steam enters the first turbine at 8 MPa and 500 C and leaves at 3 MPa. Steam is then reheated at a constant pressure to 500 C before it expands to 20 kPa in the low-pressure turbine. Assuming that heat is being added to the boiler from a high temperature source at 1800 K and the condenser is transferring heat to a temperature sink at 300 K. 1. Investigate the effect of changing pump efficiency on the overall thermal efficiency of the thermodynamics cycle (Hint: You will assume different values for the isentropic pump efficiency such as: 70%, 80%, 90%, 95%, and 100%, then observe how it will change the thermal efficiency of the cycle). Representing the results in a plot is recommended.

In a Rankine cycle with reheating, the steam leaves the boiler at 2.5 MPa and 600 ºC and enters the high pressure turbine where it expands to a pressure of 1 MPa to be then subjected to a reheating process from where it leaves at 1 MPa and 600 ° C. The steam at these conditions enters the low pressure turbine and expands up to the condenser pressure of 50 kPa. The heat that is extracted in the condenser is 1500 kJ / s. If the adiabatic efficiency of the turbines and the pump is 95%, determine the total heat flow in kJ / s delivered to the boiler.
