Carbon dioxide enters an adiabatic compressor at 100 kpa and 300 k at a rate of 0.5 kg/s and leaves at 600 kpa and 450 k. neglecting kinetic energy changes, determine (a) the volume flow rate of the carbon dioxide at the compressor inlet (b) the power input to the compressor.

a)

b)

Explanation:

part a)

inlet volume of air V1 is given as

putting all value in the above formula

we know that  volume of flow rate

part b

we know that total energy remain constant, so we have

E_in - E_out = Change in energy in system

E_in = E_out

therefore

the power input to the compressor is

be subject to a force andchange its motion
