Suppose you have a kitchen scale food dryer and you want to prepare dried zucchinis. You prepare zucchini samples uniformly cut in rectangular strips of $2$ cm x $10$ cm$,$ and place them on flat gratings over which dry hot air is blown with a velocity of $6$ m$/$s parallel to the long edge of the strips. If you operate the equipment at $80\backslash$deg C and $1$ atm, determine rate of evaporation of water in kg$/$s from both sides of a zucchini strip. You can assume the zucchini strips and air are kept at constant temperature thoughout the operation and take the diffusivity of water vapor in air as $0\mathrm{.}263$x$10^-4$ m$^2/$s
