Latent heat Transfer of heat from the ground upward by the vertical gradient of moisture carrying heat of vaporization. [Pg.134]

The heat-transfer process involves (1) latent heat transfer owing to vaporization of a small portion of the water and (2) sensible heat transfer owing to the difference in temperature of water and air. Approximately 80 percent of this heat transfer is due to latent heat and 20 percent to sensible heat. [Pg.1162]

Sensible heat transfer, Btu/hr. Condensation or latent heat transfer, Btu/hr. [Pg.81]

Reduce the rate of latent-heat transfer from the steam. [Pg.149]

The heat transfer capacity is larger than that compared to sensible or latent heat transfer (and this can give very high heat transfer coefficients). [Pg.99]

The heat transfer through membrane material takes place by conduction and the latent heat transferred by vapor flow through the membrane, which is small and could be neglected. The equation for heat transfer through the membrane can be written as [Pg.527]

Equation (57c) implies that the latent heat transferred from the surface by vaporization must be transported to the surface by conduction. For condensation, a development completely analogous to this would apply, but the heat must be transferred from the surface to the interior of the liquid. [Pg.356]

Cooling water has the highest potential due to the latent heat transfer but pressurization in the cooling loop is essential. Therefore heat transfer oil based cooling concepts are most practical. [Pg.458]

The basic equations covering combined mass- and heat-transfer phenomena have been covered in the literature. The analysis combines the sensible and latent heat transfer into an overall process based on enthalpy potential as the driving force. [Pg.97]

The interfacial boundary condition may be written in terms of the convective heat transfer of sensible heat, latent heat transfer due to evaporation, and, if the surface temperature is high enough, radiant heat transfer. Mathematically, the surface boundary condition is [Pg.76]

This calculation is typical, in that 94% of the heat is liberated at the 320°F condensing temperature of the saturated steam. Another way of stating the same idea is that a steam reboiler depends on latent-heat transfer, and not on sensible-heat transfer. [Pg.89]

Cooling towers work by moving a predetermined flow of ambient air through the tower with large fans. A small amount of the water is evaporated by the air thus, through latent heat transfer, the remainder of the circulated water is cooled. [Pg.254]

The enthalpy conservation equation of the multiphase medium, obtained from the sum of the appropriate balance equations of the constituents includes the heat effects due to phase changes and hydration (dehydration) process, as well as the convectional and latent heat transfer, [Pg.93]
