A large volume of pure gas $B$ at $2$ atm pressure is flowing over a surface from which pure $A$ is vaporizing. The liquid A completely wets the surface, which is filter paper, and the vapor pressure of A at $298K$ is $0\mathrm{.}20$atm. The $h_{m,y}$ has been estimated to be ${6\mathrm{.}78}^{**}{10}^{-5}$kmo$\frac{l}{s{m}^2}.$ Calculate flux of A and the value of $h_{m,p}$ and $h_{m,c}.$
