A room is to be maintained at 25°C dry bulb temperature and 55% relative humidity under the following conditions: the outdoor conditions (34°C DBT and 30°C WBT); Sensible and latent heat load of the persons and infiltration in the room are 5100 W and 3400 W respectively; the air is 1250 m/h and the mass of the fresh air is 5000 kg/h. (Take SHG for glass and light 2300 W and 1.2 kW respectively). By using psychometric chart, calculate: (a) the sensible heat factor. (b) Grand total heat. (Where: DBT= Dry Bulb Temp. ;WBT=Wet Bulb Temp. ; and SHG-Sensible Heat Gain)
