An engine operates on the reversible cycles as shown in the figure. The work output from the engine (in kJ/cycle) is _______(correct to two decimals)

1. 52.5 kJ/cycle
2. 60.5 kJ/cycle
3. 62.5 kJ/cycle
4. 66.5 kJ/cycle

Correct Option: C

Work output = ∫pdv

W =	1	× (2 - 5 - 2)(650 - 900)
	2

W =	1	× (0.5)(250)
	2

W = 62.5 kJ/cycle
