Consider a Rankine cycle with saturated steam leaving the boiler at a pressure of 2 MPa and a condenser pres- sure of 10 kPa.
(a) Calculate the thermal efficiency of the ideal Rankine cycle for these operating conditions.
(b) If the net reversible work for the cycle is 0.5 MW, calculate the required flow rate of cooling water supplied to the condenser at 15°C with an allow- able temperature rise of 10°C.
(c) Design a shell-and-tube heat exchanger (one-shell, multiple-tube passes) that will meet the heat rate and temperature conditions required of the con- denser. Your design should specify the number of tubes and their diameter and length.
