Where necessary, assume air as an ideal gas and consider R = 287J/(kg.K), Cp = 1005 J/(kg.K), Cv = 718 J/(kg.K). A nozzle is a device that is used to increase the velocity of a fluidby varying the cross-sectional area. At the last section of a jetengine (Fig Q1.a, section 5), air with a mass flow rate of 50 kg/s ata pressure of 500 kPa and a temperature of 600 K enters a nozzlewith an inlet cross-sectional area of 5 m2. The exit area of thenozzle is 20% of its inlet area. The air leaves the nozzle at avelocity of 300 m/s. The nozzle is not well-insulated and duringthis process, 5 kJ/kg heat is lost. (iv) Determine the temperature of the air as it leaves the nozzle.(v) Calculate the pressure of the air as it leaves the nozzle.

Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot.
