[CLO-4] A rigid tank initially contains 50 L of air (Ideal gas) at 400 kPa and 25°C. A wheel connected to a shaft, as shown in the figure, is rotated until 150
kJ of work is done on the air. During the same process, 30 kJ of heat is lost from the tank. Determine the final temperature of the air. Tako R = 0.287
KJ/kgK, Cp = 1.005 kJ/kgK, and Cy = 0.718 kJ/kgK. Take 1 L = 0.001 m3.
