500 kg of air is supplied per minute to an auditorium maintained at 21°C and 40% RH. The outside air at 5°C DBT and 60% RH is first passed over heating coils and is heated until its WBT is equal to the room WBT. It is then passed through an adiabatic saturator and is finally heated to 45°C before being supplied to the room. Determine a) the heat added in both the heating coils b) the mass of water evaporated in the air washer

Question
500 kg of air is supplied per minute to an auditorium
maintained at 21°C and 40% RH. The outside air at 5°C DBT
and 60% RH is first passed over heating coils and is heated
until its WBT is equal to the room WBT. It is then passed
through an adiabatic saturator and is finally heated to 45°C
before being supplied to the room. Determine
a) the heat added in both the heating coils
b) the mass of water evaporated in the air washer.
