4. After being heated in the combustion chamber of a jet engine, nitrogen at low velocity, 690kPa, and 877°C enters the jet nozzle. (a) Determine the maximum velocity, in m/sec, that can be obtained from the nozzle if the nitrogen discharges from it at 80kPa, and (b) determine the diameter at the exit necessary to accomodate a mass flow rate of 10 kg/sec.
