Question $2$ Mass convection

Dry air at $15C$ and $85$kPa flows over a $2-$m$-$long wet water surface with a free stream velocity of $3\frac{m}{s}.$ Determine the average mass transfer coefficient in $\frac{m}{s}.$ The mass diffusivity of water in air

can be calculated by using the following equation $(T$ in kevin, $P$ in atm.$)$: Check the picture for the equation written in Purple.
