Lecture

Heat Transfer: Latent Heat and Enthalpy

Description

This lecture covers the concepts of latent heat and enthalpy in the context of heat transfer. It explains how the overall heat content of humid air is linked to changes of state, particularly evaporation. The instructor discusses the importance of latent heat in processes like evaporation and how it affects the heat content of moist air. The lecture also delves into the role of sensible heat and water evaporation in determining the heat content of humid air. Various factors influencing thermal comfort, such as air temperature, relative humidity, and clothing, are explored in detail, along with mechanisms like radiation, air speed, and sweat production.
