SENSIBLE HEAT, LATENT HEAT and SPECIFIC HEAT

WebThe transfer of thermal energy due to the temperature difference between two objects is what is known as heat. Heat is a form of energy in transit, and once transferred, it is stored as internal energy. There are four main methods of heat transfer: conduction, convection, radiation, and the absorption or release of latent heat. WebLatent heat is the heat required for an object to change phase (melt, boil, freeze, etc.). This energy is closely related to enthalpy. In figure 1, very cold ice has heat added to it. The temperature goes up, so that's sensible heat, but once it starts melting, that heat is latent heat (and is represented by the flat parts of the line, during melting or evaporation). WebDec 18, 2011 · Specific latent heat means the amount of heat energy needed to convert a phase to another phase of a unit mass of a substance completely. Sensible Heat.

The 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 change such as the melting of ice, the temperature of the system containing the ice and the liquid is constant until all ice has melted. The terms latent and sensible are correlative.

Webheat, energy that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter … WebThe Sensible Heat Ratio - SHR - is used to describe the ratio of sensible heat load to total heat load and can be expressed as: SHR = qs / qt. = qs / (qs + ql) (1) where. SHR = sensible heat ratio (ratio of sensible heat load to total heat load) qs = sensible heat load (kW, Btu/hr) qt = total heat load - sensible heat and latent heat (kW, Btu/hr)
