EXAMPLE $8$

A pure nitrogen carrier gas flows parallel to the $0\mathrm{.}6m^2$ surface of a liquid acetone in an open tank. The acetone temperature is maintained at $290K.$ If the average mass$-$transfer coefficient, $k_c,$ for the mass transfer of acetone into the nitrogen stream is $0\mathrm{.}0324\frac{m}{s},$ determine the total rate of acetone release in units of $kg*mo\frac{l}{s}.$
