Why would you use an intercooler between compressor stages?
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 is increased. Of the four statements listed above (a) 1 alone is correct (b) 2 and 4 are correct (c) 1,2 and 3 are correct (d) $1,2,3$ and 4 are correct
A two-stage reciprocating air compressor delivers 4.2 kg of free air at 0.95 bar and 22°C. The compressor delivers air at 13 bar with perfect intercooling between the two stages. The mechanical efficiency is 0.75. Neglecting the clearance volume, determine: i) the capacity of the electric motor. ii) the % saving in work if two-stage intercooling is compared with a single-stage compressor between the same limits.
