air behaves as an
ideal gas with R = 0.287 k J k g K.
- A compressor operates at steady state and takes in air from
ambient 0 kPa, gage and 300 K. The outlet pressure is 60 kPa, gage
and 300 K. Determine:
- the mass flow rate if the inlet area is 10 cm2 and
the inlet pressure is -3 kPa, gage.
- the minimum outlet temperature that is possible for this
compressor.
- the isentropic efficiency of the compressor, assuming no heat
loss.
- if there is a heat loss of 20 kJ/kg, the work required to run
the compressor, and the new isentropic efficiency.
outlet is 500K
