2. A group of twenty executives attend a board meeting in a room which measures 20 ft by 20 ft and has a 10 ft ceiling. Assume that each person occupies 2.5 ft and gives out about 375 Btu of heat per hour. Calculate the air temperature rise occurring within 15 min of the start of the conference if the room is completely sealed and insulated. Take c, for air as 0.1715 Btu/lbm°F.
