Benzene-free air at 25C and 101.3 kPa enters a 5-cm-diameter tube at an average velocity of 5
Question:
Benzene-free air at 25°C and 101.3 kPa enters a 5-cm-diameter tube at an average velocity of 5 m/s. The inner surface of the 6-m-long tube is coated with a thin film of pure benzene at 25°C. The vapor pressure of benzene (C6H6) at 25°C is 13 kPa, and the solubility of air in benezene is assumed to be negligible. Calculate
(a) The average mass transfer coefficient in m/s,
(b) The molar concentration of benzene in the outlet air,
(c) The evaporation rate of benzene in kg/h.
