a. Calculate the thermal efficiency and turbine-exit quality for an Ideal Rankine Cycle
where the steam exits boiler at 5MPa, 450C and the condenser pressure is 15 kPa.
Draw the systems and the Ts diagram for the process.
b. Calculate also the thermal efficiency and turbine-exit quality if the system is modified
to an Ideal Reheat Rankine Cycle where the reheat takes place at 1 MPa and the
steam leaves the reheater at 500C. Draw the systems and the Ts diagram for the
process and discuss your findings of these two systems.
