Answer to Question #126099 in Thermal Power Engineering for Sahil

Question

Air at 1 atm absolute pressure, 38oC and 80% relative humidity is to be cooled to 18oC
and fed into a plant area at a rate of 510 m3
/min (STP). Calculate the rate (kg/min) at which
water condenses

Answer 1

To Calculate the rate (kg/min) at which water condenses, we need to apply the concepts that are related to ideal gas laws, and mass flow rate.

Data are given by;

Flow rate (air water vapor mixture)=

Note that the 1 atm absolute pressure is

Now, to calculate the mass flow;

To the mass flow rate at which water condenses
