A porous tube of 1 m long and 2 cm diameter is partially submerged in water at 25 °C. Given its porosity, water wets the interior of the tube. The tube is filled with air at 25 °C and flows at a speed of 4 m/s. Calculate the air humidity at the end of the tube as a function of: a) Changing temperature between 5 and 45 °C. b) Changing tube length between 0.1 and 5 m. c) Changing air speed between 1 and 10 m/s. d) Changing tube diameter between 1 and 5 cm. e) Discuss the effect of this variables in the air humidity and the mass transfer phenomena.
