Question
A The rate of evaporation of water from a surface maintained at a
temperature of 60°C is 2.71 x 104 kg/s m². What will be the rate of
evaporation of benzene from a similar surface but maintained at 26°C.
If the effective film thickness is the same in both the cases.
Given:
v.p of water at 60°C = 149 mm Hg
v.p of benzene at 26°C = 99.5 mm Hg
Diffusivity of air-water vapour at 26°C = 2.6 x 10-5 m²/s
Diffusivity of air-benzene vapour at 60°C= 0.98 x 10-5 m2/s
Atm. pressure in both the cases:
1.013 x 105 N/m2
