I need the answer as soon as possible
When the outdoor temperatures are 40 ° C
DBT and 26 ° C WBT , an air conditioning
system is used to maintain a building at 25 °
C DBT and 50 % RH. In a conditioned
building , the sensible load is 100 kW , while
the latent load is 20 kW. 14% of the outdoor
air is mixed with 86% of the return air on a
mass basis. Before it is supplied to the
conditioned zone, the mixed air is cooled by
a cooling coil. During this process, the
temperature of chilled water inside the coil
increased by 5.6 ° C. (1) The condition of
the air after supply, (2) The required cooling
capacity in tons, (3) The rate at which chilled
water passes through the cooling coil, (4)
The By-pass factor of the cooling coil, and
(5) The air flow rate required for ventilation .
