I’m not quite understanding one formula from the drying chapter in Principles of Chemical Engineering

In Chen Minheng’s second edition of Principles of Chemical Engineering, Volume 2, on page 328, why isn’t the yellow-highlighted part the latent heat of water?

The latent heat of water is the heat required for vaporization; the sensible heat mentioned here refers to the enthalpy brought in by the liquid water added. I don’t see any calculation using the specific heat capacity of water

Looking closer, it’s just heat balance

Thank you to the two people above for their advice. I think my misunderstanding regarding enthalpy lies in the fact that the enthalpy of a gas is based on dry gas, yet it refers to the enthalpy value of moist gas~
