WebThe term is used in contrast to a latent heat, which is the amount of heat exchanged that is hidden, meaning it occurs without change of temperature. For example, during a phase … WebAnswer (1 of 4): First you should know what saturated state means here. Water in saturated state is in equilibrium with water vapor, that means at a specified condition of temperature and pressure water is at its maximum possible temperature so that any further heating of it will start increasing...
WebHeat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit area per unit time.In SI its units are watts per square metre (W/m 2).It has both a direction and a magnitude, and so it is a vector quantity. To define the heat flux at a certain point in space, one takes the limiting case …
