Assignment:
A wetted-wall experimental setup consists of a glass pipe, 50 mm in diameter and 1.0 m long. Water at 300 K flows down the inner wall. Dry air enters the bottom of the pipe at the rate of 1.04 m3/min, measured at 308 K and 1 atm. It leaves the wetted section at 308 K and with a relative humidity of 21.5%. With the help of equation (2-83), estimate the average mass-transfer coefficient, with the driving force in terms of molar fractions.
Provide complete and step by step solution for the question and show calculations and use formulas.
