Question
b) Air enters a compressor operating steadily at 101.3 kPa and 300 K, with a volumetric flow
rate of 10 m3/min and exits at 1300 kPa and 420 K. Heat transfer occurs at a rate of 5 kW
from the compressor to its surrounding. Assuming air as an ideal gas and neglecting kinetic
and potential energy effect, determine;
i.
the volumetric flow rate of air at outlet, m3/min and
the mass flow rate of the air, kg/s
ii.
iii.
the compressor power input, kW.
For the air takes R
0.287 kJ/kgK and c,
1.005 kJ/kgK
