Assignment:
Water flows down the inside wall of a 25-mm-ID wetted-wall tower of the design shown in Figure, while air flows upward through the core. Dry air enters at the rate of 7 kg/m2-s. Assume that the air is everywhere at its average conditions of 309 K and 1 atm, the water at 294 K, and the mass-transfer coefficient constant. Compute the average partial pressure of water in the air leaving a tower 1-m-long.
Provide complete and step by step solution for the question and show calculations and use formulas.
