[Solved] A simple Rankine cycle operates the Boiler at 3 MPa with an outlet temperature of 350°C and the Condenser at 50 kPa. Assuming ideal operation and processes, what is the thermal efficiency of this cycle?

Q.	A simple Rankine cycle operates the Boiler at 3 MPa with an outlet temperature of 350°C and the Condenser at 50 kPa. Assuming ideal operation and processes, what is the thermal efficiency of this cycle?
A.	7.7
B.	17.7
C.	27.7
D.	37.7
Answer» C. 27.7
Explanation: fixing the states; h1 = 340.5 kj/kg, h2 = h1 + v1 (p2 – p1) = 343.5 kj/kg, h3 = 3115.3 kj/kg, s3 = 6.7428 kj/kg – k, x4
