Question

When humidity changes, does entalpy chande as well?

Answer 1

Yes, with change in humidity, enthalpy changes as well.

Step-by-step explanation:

This can be explained by the given relation:

H =
`0.24T_(b)(w(0.444T_(b) + 1061 ) )`

where

H = enthalpy (in Btu/lb)

w = specific humidity (lb-water/lb-dry air)

`T_(b)` = dry-bulb temperature (in
`F^(\circ)`)

The above relation clearly explains that if temperature does not vary, enthalpy is in direct proportion with the humidity.

So, any change in humidity results in a corresponding change in the enthalpy.
