Air enters an adiabatic compressor at 104 kPa and 292 K and exits at a temperature of 565 K. Determine the power (kW) for the compressor if the inlet volumetric flow rate is 0.15 m3/s. Use constant specific heats evaluated at 300 K.

Explanation:

An adiabatic compressor is modelled as follows by using the First Law of Thermodynamics:

The power consumed by the compressor can be calculated by the following expression:

Let consider that air behaves ideally. The density of air at inlet is:

The mass flow through compressor is:

The work input is:

c

explanation:

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
