In a cyclic process, heat transfers are + 14.7 kJ, –25.2 kJ, –3.56 kJ and + 31.5 kJ. What is the net work done in the net cyclic process ?
A
10 kJ
B
– 10 kJ
C
–17.44 kJ
D
- 17.44 kJ
Answer
–17.44 kJ
Explanation
Solution
In the cyclic process DWcyc + Dqcyc = 0
or DWcyc = – Dqcyc = – [14.7 – 25.2 – 3.56 + 31.5] kJ
or DWcyc = – 17.44 kJ
