[6 Marks Q4) Based on the following information, calculate the net heat gain in Al Fikr computer lab during (i) Winter season, and (ii) Summer season. [15 Marks Lab dimensions: 30m x 20m x 3 m. Internal heat gain : 20 KW from people +6 KW from lighting + gains from 200 computers. Heat gain from each computer :200 W. Power of exhaust fan: 500 W Temperature inside the lab : 15 C Outside temperature during winter : 6 Outside temperature during summer: 40C Fan pressure=100 pa Fan efficiency 80% Net heat gain= Total heat - Heat lost [6 Marks Q4) Based on the following information, calculate the net heat gain in Al Fikr computer lab during (i) Winter season, and (ii) Summer season.
