A fan drawing electricity at a rate of 1.5kw is located within rigid enclosure of 3m*4m*5m. Enclosure is filled with air at 27oC, 0.1 MPa. The fan operates for 30 minutes. Assume the ideal gas model, determine
a) mass (in kg) b) final T (in oC) and c) final pressure (in MPa). There is no heat transfer between the enclosure and surroundings. Ignore the volume occupied by the fan and assume the fan stores no energy.
