Fresh air at 21.1 C in which partial
pressure of water vapor is 0.018
atmosphere is blown at the rate of 214
m3/h first through a preheater and then
adiabatically saturated in spray chambers
to 100% saturation and again reheated
this reheated air has humidity of 0.024 kg
water vapor per kg dry air. It is assumed
that the fresh air and the air leaving the
re-heater have the same percentage
humidity.

spray-chamber and re-heater
b- Heat requirement for preheating and
re-heating
