When the temperature of air leaving the inter-cooler, in a two stage compression with inter-cooler, is ________ the original atmospheric air temperature, then the intercooling is known as perfect or complete intercooling.

A Equal to
B Less than
C More than
D None of these

Correct Answer: Equal to

When the temperature of air leaving the inter-cooler, in a two stage compression with inter-cooler, is equal to the original atmospheric air temperature, then the intercooling is known as perfect or complete intercooling.
