Question
Q1: Moist air at 40°CDBT, 20°CWBT, and standard atmospheric pressure is
humidified adiabatically to 25 CDBT and 70% RH. Find the amount of moisture and
heat added per Kg of air. (answer without using of psychrometric chart).
Q2: A room is to be maintained at 22°C db and 50%RH has total heat loss of 7.5
kW of which 80% is sensible heat, when outdoor at 5 °C and 80% RH. If the design
difference between supply and room air temperature is 10°C DBT and 50% fresh
air, find the capacities of heating coil, and humidifier used a tap water at 10 "C.
Q3: A room is maintained at 22°C and 50%RH has a wall consist of common brick
finished internally with gypsum plaster and externally with 15mm cement plaster.
The outside conditions are 2°C, 75% RH. Find the thickness of common brick
required for preventing moisture condenses on the wall.
