Question
A compressor draws in 0.1 m/s of air at atmospheric conditions of 1.013 bar and 22°C and
delivers it to a large receiver in which the air stabilises at a temperature and pressure 28°C
and 310 kPa gauge.
The air then discharges back to atmosphere through a converging diverging nozzle located
in the side of the tank. Ignoring losses in the nozzle.
Determine the:
i. Mass flow of air entering and leaving the receiver.
ii. The pressure, temperature and velocity at the throat.
iii. The throat diameter of the nozzle.
For air take R = 287 kJ/kg.K and y = 1.4
Isentropic Flow tables are needed for use with this question.
