where [e.sub.0] is the reference pressure (611.12 Pa), [l.sub.[upsilon]0] is the latent heat of vaporization at 0[degrees]C (2.5008 x [10.sup.6] J [kg.sup.-1]), [R.sub.[upsilon]] is the individual gas constant for water vapor (461.2 J [kg.sup.-1] [K.sup.-1]), [T.sub.0] is the reference temperature at the triple point of water (273.16 K), T is the in situ temperature (K), c is the specific heat of liquid water at 0[degrees]C (4,215 J [kg.sup.-1] [K.sup.-1]), and [c.sup.vapor.sub.p] is the specific heat of water vapor at constant pressure (1,844.8 J [kg.sup.-1] [K.sup.-1]) (Miller 2015).
Figure 1 shows the curves of the latent heat of vaporization of water of crambe fruits at 25, 30, 35, 40, and 45[degrees]C.
Latent heat of vaporization is a constraint not implemented in Workbench and is calculated separately by mass-fraction-weighted latent heat of vaporization of single components.
As can be seen in Table 3, RON 71 naphtha-based fuel and reformate have a low latent heat of vaporization compared to TRF; on the opposite side, ethanol has a huge latent heat of vaporization, more than twice that of the TRF and three times that of the RON 71 naphtha-based fuel.
Thus, the gas gives up the latent heat of vaporization and moves heat from the input to the output end of the heat pipe.
Where, [m.sub.1] is the total mass including the stock, [C.sub.p] is the specific heat of the paper, T the boiling point of the respective carrier fluid (water or solvent), [m.sub.2] the mass corresponding to the ink film and [delta]H is the latent heat of vaporization of the solvent.
In this case, the latent heat of vaporization from the primary kiln's water vapor is captured by the heat exchangers and is transferred to the secondary kiln.
This phenomenon, known as the latent heat of vaporization, is the same reason a warm breeze feels cool after a swim.
