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. Assume an iso-entropic (and adiabatic) process and neglect kinetic energy and potential energy changes. Process D-A: The saturated vapor then enters a condenser where it is condensed at a constant pressure process back to its original state.

Scenario (1) 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. Task 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.

A steam power plant operates on the reheat Rankine cycle. as shown in the schematic diagram (Fig. Q 2). Steam enters the high-pressure turbine at 12.5MPa and 550o C at a rate of 7.7 kg/s and leaves at 2 MPa. Steam is then reheated at constant pressure to 450o C before it expands in the low-pressure turbine. The isentropic efficiencies of the turbine and the pump are 85% and 90%, respectively. Steam leaves the condenser as a saturated liquid. If the moisture content of the steam at the exit of the turbine is not to exceed 5%, then make all the necessary assumptions and determine(a) the condenser pressure,(b) the net power output, and(c) the thermal efficiency.Draw an accurate T-s diagram of the cycle and label all the property values on this diagram.
