Right Answer is: C
SOLUTION
Explanation:
Intercooler:
- The intercooler is a constant pressure device which cools the working fluid at constant pressure.
- In a two or multistage air compressor, an intercooler is always placed between the low pressure (L.P.) and high pressure (H.P.) cylinder.
- The purpose of an intercooler is to reduce the work input given to the compressor to reach the same pressure as can be reached by a single compressor.
- Here in the below diagram, it can be clearly seen that using the intercooler green shaded region is the amount of work saved while compression by multi-staging.
