Assignment:
In a laboratory experiment, air at 300 K and 1 atm is blown at high speed parallel to the surface of a rectangular shallow pan that contains liquid acetone (C3,H6,O), which evaporates partially. The pan is I m long and 50 cm wide. It is connected to a reservoir containing liquid acetone, which automatically replaces the acetone evaporated, maintaining a constant liquid level in the pan. During an experimental run, it was observed that 2.0 L of acetone evaporated in 5 min. Estimate the mass-transfer coefficient. The density of liquid acetone at 300 K is 0.79 g/cm3; its vapor pressure is 27 kPa (Perry and Chilton, 1973).
Provide complete and step by step solution for the question and show calculations and use formulas.
