If the air is then circulated at the rate of 330 ft3/min by the blower, how much thermal energy is transferred per hour. Note: the specific heat of air at constant pressure is 0.250 Btu/lboF, the density of air is 0.0806 lb/ft3 at atmospheric pressure.
A vessel of 5 m3 capacity contains air at 100 kPa and temperature of 300K. S ome air is removed from vessel so as to reduce pressure and temperature to 50 kPa and 7C respectivel y. Find the amount of of air removed and volume of this mass of air at initial states of air. Take R = 287 J/kg.K for air.
