Question #127549

Outdoor at 5°CDBT and 60%RH is passed through a heating coil which gives 11kW

energy to the air, then humidified by sat steam (at 110oC) with a rate of 0.33kg/min, find

the final air dry and wet bulb temperatures for unit mass rate.

energy to the air, then humidified by sat steam (at 110oC) with a rate of 0.33kg/min, find

the final air dry and wet bulb temperatures for unit mass rate.

Expert's answer

Here in the question , DBT= , RH=60 %,

from the psychometric chart we find

H=15 J/g, Humidity ratio=0.03

humidified by steam at 110 ^{o}C and mass flow rate is 0.33 kg/min

Total energy supplied=11kJ/s

water removed in dryer=

from psychometric

Total energy supplied = 268-35=233

so final condition for air

DBT=35^{o}C, WBT= 33 ^{o}C using psychometric
