A fan drawing electricity at a rate of 1.5 kW is located within a rigid enclosure, measuring 3m x 4m x 5m. The enclosure is filled with air, initially at 27 degrees C, 0.1 MPa. The fan operates steadily for 30 minutes. Assuming ideal gas behavior, determine for the air
a. The mass, in kg
b. The final temperature after 30 minutes, in degrees C. Do this calculation via two methods and compare them: i) assuming a constant specific heat at 300 K and ii) using the ideal gas air tables
c. The final pressure, in MPa
There is no heat transfer between the enclosure and the surroundings. Ignore the volume occupied by the fan itself and assume the fan stores no energy.
