Agas expands through a convergent-divergent nozzle at a rate of 181 kg/min to an actual temperature of 221 °c. the nozzle efficiency is 89%, while the throat pressure is 1 581 kpa. the isentropic temperature drop through the nozzle is 298 °c. take gamma for air as 1,4 and r for air as 0,288 kj/kg. k. ignore the velocity of the gas at the inlet and calculate the following quantities: at the nozzle inlet: 5.1 the absolute temperature of the gas 5.1.1 the pressure of the gas in kpa 5.1.2 (2 x 3) (6) 5.2 the value of cp for the gas (3) at the throat of the nozzle: 5.3 the absolute temperature of the gas 5.3.1 (2) 5.3.2 (2) the velocity of the gas in m/s (3) 5.3.3 the specific volume of the gas 5.4 at the nozzle exit: 5.4.1 the absolute isentropic temperature of the gas 5.4.2 the velocity of the gas in m/s
