2. Air (1atm, 298K) enters a 5cm (diameter), 6m (long) tube at 5m/s. The inside of
the tube is coated with a thin film of pure benzene (Pvap= 13 kPa; negligible
solubility in air). What is:
a.The average mass transfer coefficient (in m/s)?
b. The concentration of benzene in the outlet air (in kmol/m3)?
c. The rate of evaporation of benzene (in kg/hr)?
