Question: a the universal gas constant has a value of 8314...

Question details

(a) The universal gas constant has a value of 8314 J/kmol-K. (b) All gases in the problems should be taken to be perfect gases with constant specific heats, unless specifically stated otherwise. (c) Air as a perfect gas has a gas constant, R 287 J/kg-k, a specific heat at constant pressure of 1005 J/kg-K, a specific heat ratio, y- 1.4. (d) One atmosphere is equal to 101.325 kPa.
Problem 2 A convergent nozzle with an exit diameter of 1/16 inch is fed air from a large tank. Please calculate the required tank pressulxe Ipsigl to choke the nozzle (i.e. to achieve sonic condition at the nozzle exit). If the air temperature in the tank is 70 °F, please calculate the air velocity Im/s] at the exit of the nozzle and the corresponding air mass flow rate [kg/s).
