An ideal Rankine cycle with double reheat operates the boiler at 12 MPa, the reheater at 5 MPa and 2.0 MPa, and the condenser at 0.01 MPa. The temperature at the boiler and reheater outlets are maintained at 400°C. a) Determine the total rate of heat transfer per unit mass in the reheaters, and b) the thermal efficiency of this cycle.

PLEASE FOLLOW THE INSTRUCTION. 

Instruction:
a. Draw a schematic diagram of each problem with labels of states of a substance;
b. For uniformity purposes, assign STATE 1 at the inlet of a high-pressure turbine. The states must be
arranged in a chronological order;
c. Plot each cycle in a t-s diagram with the states consistent to the states assignment in the schematic
diagram;
d. Show a detailed solution of each problem.
