Choose an option
Answer
Correct Answer: Equal to the sum of works in L.P. and H.P. cylinders
Explanation
Concept/ApproachEach cycle comprises compression (and associated processes) in the low-pressure (L.P.) stage plus in the high-pressure (H.P.) stage. The indicated work per cycle is the sum of the indicated works of both stages, accounting for intercooling and valve actions.
Final AnswerEqual to the sum of works in L.P. and H.P. cylinders
