The release of the latent heat of condensation occurs when water vapor changes phase to liquid water, which requires the air to be saturated. However, for strong updrafts, analysis of the vertical momentum equation reveals that local buoyancy from the release of latent heat must be present to generate significant vertical wind speeds and ...

Energy transfer from latent heat to sensible heat. Heating up the air by condensing out the water vapor yields a temperature increase defined by the following energy balance equation (1) Note that this equation assumes . all. of the water vapor in the air parcel has condensed out. The temperature increase due to latent heat conversion to ...

Thus, the latent energy is released over a range of about 10 F, and the formulation above is a step-change simplification of a continuous process. Using this definition of latent heat, a more general equation for combustion efficiency is:

The number of tubes required are found by determining the total heat transfer required to condense 0.15 kg/s of steam with the latent heat found above: hfg = 2431 kJ/kg. The total heat transfer required is. Since each tube has a heat transfer of 2.656x104 W, the number of tubes required is simply the ratio of the two heat transfers.

(Specific latent heat of fusion of water = 3.3 x 105 J kg-1) (Specific latent heat of vaporisation of water = 2.25 x 106 J kg-1) Solution: Break the calculation up into the various stages of heating. 1 - heat raises temperature of the ice until it reaches its melting point - 0oC. 2 - ice melts to form water at 0oC

The magnitude of dq is the latent heat Lvl (J kg-1) multiplied by an incremental change in saturation mixing ration, drvs (kg kg-1 – this is really dimensionaless). The units are therefore J kg-1. dq = -Lvldrvs = cpdT - dp.
