Open Tank Evaporation
Open Tank Evaporation
(OP)
What is the resulting RH of air in a warehouse heated to 50-55F with a 35F open tank of water?
Knowns:
Building is 200x200
Open tank is 100x100
Ambient Outdoor 10F/20%RH
Indoor 50-55F
RH of Air?

RE: Open Tank Evaporation
Is the water kept at 35F, or will it warm to ambient?
Airflow over the tank?
Hypothetically, with no dehumidification (closed system) the wetbulb of the space will eventually hit the temperature of the water.
RE: Open Tank Evaporation
I'm asked to evaluate the insulation properties of the enclosure to determine if condensation will occur.
So, if no outdoor air is introduced you think the Wet bulb of the space will reach the water temp?

RE: Open Tank Evaporation
This problem of yours is highly time dependent and needs to factor infiltration and ventilation to solve.
RE: Open Tank Evaporation
That will influence the heat transfer most. If you have two different temperature heat sinks, you will have air motion.
