Thermodynamics ENGG*3260, Fall 2023

Assignment # 9 Solution
Assigned: Friday, November 10, 2022
The questions in this assignment are mostly chosen from the 8th edition of Cengel's
Thermodynamics textbook. Similar questions can be found in 9th edition as well.

1. Heat rejected decreases; everything else increases.

2. A steam power plant operates on a simple ideal Rankine cycle between the specified pressure
limits. The thermal efficiency of the cycle and the net power output of the plant are to be
determined.

3. A steam power plant that operates on a simple ideal Rankine cycle is considered. The quality
of the steam at the turbine exit, the thermal efficiency of the cycle, and the mass flow rate of
the steam are to be determined.

4. A steam power plant that operates on a simple nonideal Rankine cycle is considered. The
quality of the steam at the turbine exit, the thermal efficiency of the cycle, and the mass flow
rate of the steam are to be determined.

5. The pump work remains the same, the moisture content decreases, everything else increases.

6. A steam power plant that operates on an ideal reheat Rankine cycle between the specified
pressure limits is considered. The pressure at which reheating takes place, the total rate of
heat input in the boiler, and the thermal efficiency of the cycle are to be determined.
