where [l.sub.[upsilon]] is the latent heat of vaporization at temperature T (J [kg.sup.-1]), [l.sub.[upsilon]] is its value at 0[degrees]C (2.5008 x [10.sup.6] J [kg.sup.-1]), [l.sub.[upsilon]1] is the slope of a linear function (-2,369), and T is the temperature ([degrees]C) (Miller 2015).
Alcohols are added to replicate the latent heat of vaporization of the E10 Gasoline.
Latent heat of vaporization is assessed by using linear mass blending rule.
When that happens, the liquid picks up the latent heat of vaporization. The gas has a higher pressure, moves inside the sealed container to a colder location where it condenses.
The heat pipe is self-contained device for transferring heat in which the latent heat of vaporization is exploited to transfer heat over long distance with a corresponding small temperature difference (1).
Re is the Reynolds number based on [D.sub.e], [h.sub.fg] is latent heat of vaporization, [L.sub.p] is effective plate length, p is pressure, [p.sub.cr] is critical pressure, and [beta] is the chevron angle in degrees.
This is the coldest cryogenic fluid (-269[degrees]C/-452[degrees]F) and has a very low latent heat of vaporization of about 9 Btu/lb.
where, [delta]T is the reduction in temperature; the subscripts m and s denote respectively the polymer melt and the solvent; [rho] is the density; [C.sub.p] is the specific heat; V is the volume; [delta][H.sub.u] is the latent heat of vaporization; [delta][H.sub.f] is the heat of fusion; and [delta][H.sub.c] is the heat of crystallization.
