The sensible heat of a thermodynamic process may be calculated as the product of the body's mass (m) with its specific heat capacity (c) and the change in temperature (): =. Joule described sensible heat as the energy measured by a thermometer. Sensible heat and latent heat are not special forms of energy. Rather, they describe exchanges of ...
The terms sensible heat and latent heat refer to energy transferred between a body and its surroundings, defined by the occurrence or non-occurrence of temperature change; they depend on the properties of the body. Sensible heat is sensed or felt in a process as a change in the body's temperature.
The ice had thus absorbed 8 “degrees of heat”, which Black called sensible heat, manifest as temperature change, which could be felt and measured. In addition to that, 147 – 8 = 139 “degrees of heat” were absorbed as latent heat, manifest as phase change rather than as temperature change. [22] [26]
Cooling load is the rate at which sensible and latent heat must be removed from the space to maintain a constant space dry-bulb air temperature and humidity. [1] [2] Sensible heat into the space causes its air temperature to rise while latent heat is associated with the rise of the moisture content in the space.
After the experiments, Thompson was surprised to observe that a vacuum was a significantly poorer heat conductor than air "which of itself is reckoned among the worst", [55] but only a very small difference between common air and rarefied air. [56] He also noted the great difference between dry air and moist air, [57] and the great benefit this ...
The Bowen ratio is calculated by the equation: =, where is sensible heating and is latent heating. In this context, when the magnitude of is less than one, a greater proportion of the available energy at the surface is passed to the atmosphere as latent heat than as sensible heat, and the converse is true for values of greater than one.
People are highly sensitive to even small differences in environmental temperature. At 24 °C, a difference of 0.38 °C can be detected between the temperature of two rooms. [4] The Predicted Mean Vote (PMV) model stands among the most recognized thermal comfort models.
The atmospheric and oceanic circulation redistributes some of this energy as sensible heat and latent heat partly via the mean flow and partly via eddies, known as cyclones in the atmosphere. Thus the tropics radiate less to space than they would if there were no circulation, and the poles radiate more; however in absolute terms the tropics ...
