Question 56
CHNAT2 marksNeeds review
Partially saturated air at 1 bar and 50 °C is contacted with water in an adiabatic saturator. The air is cooled and humidified to saturation, and exits at 25 °C with an absolute humidity of 0.02 kg water per kg dry air. Use latent heat of vaporization of water as 2450 kJ·kg
, and average specific heat capacity for dry air and water, respectively as 1.0 kJ·kg
·K
and 4.18 kJ·kg
·K
. If the absolute humidity of air entering the adiabatic saturator is
kg water per kg dry air, the value of
is __________ (rounded off to two decimal places).Log in to check the answer
