Intercooling between stages of air compression: effect on required power Statement: Intercooling in multistage air compressors saves power when compressing a given volume of air to a given final pressure (compared to no intercooling). Decide whether the statement is correct.

Concept/ApproachIntercooling removes the heat of compression between stages, returning the air toward the initial suction temperature before the next stage. This reduces the specific volume entering the next stage and reduces the work required, approaching the minimum work of isothermal compression.
