An adiabatic expansion of air occurs through a nozzle from 120 psia and 96oF to 20 psia.The final velocity is twice of the initial velocity. For an isentropic expansion (a) computethe specific volume, temperature at the exit section and (b) the velocity in ft/sec at eachsection.
Air enters an air compressor at 100 kPa and 100°C and a flow rate of 5 kg/s. If the air exits at 389 kPa and 398°C, find the power input to the
compressor If it is 85 % efficient.
