Heat of Vaporization

on . Posted in Thermodynamics

conduction convection radiant 4Heat of vaporization, abbreviated as \(H_v\), is the amount of heat needed to be consumed to vaporize a specific amount of liquid at a constant temperature.


Heat of vaporization Formula

\(\large{ H_v  =  \frac{ q }{ m }  }\)  
Symbol English Metric
\(\large{ H_v }\) = heat of vaporization \(\large{\frac{Btu}{lbm}}\)   \(\large{\frac{J}{kg}}\)
\(\large{ q }\) = heat \(\large{\frac{Btu}{lbm}}\) \(\large{\frac{J}{kg}}\)
\(\large{ m }\) = mass of substance \(lbm\) \(kg\)
