A meeting room size (10 x 8 x 4)m and 30-person capacity. The outside conditions are 48 C maximum dry bulb temperature, 32 C minimum (DBT), and 20% relative humidity. The inside design conditions are 25 C (DBT) and 50% relative humidity. If the space cooling load is 10 TR and ventilation air required is 5.0 lit/s/person, design an air duct system for supplying air.
