A air Compressor lequires a power input Of 1400 kW andask
It Operates adialatically. The air İS compressed from 300 K
and atmosp heric pressure to an exit presure of 20 atm,
and the air leaves he comp ressor at a speed of 200 m/SecT
DAssume that the air is an ideal gas and the inlet velocitey is m
negligibly small, but do not ašsume that the specific heats rl
are čonstant. if the mass flow rate is 2 kg/sec, calculate it
the air temperature at the exit in
figires.
