Consider the following statements: When air is to be compressed to reasonably high pressure, it is usually carried out by multistage compressor with an intercooler between the stages because 1. Work supplied is saved 2. Weight of compressor is reduced. 3. More uniform torque is obtained leading to the reduction in the size of flywheel. 4. Volumetric efficiency Of the four statements listed above:
