4.- En un equipo humidificador el líquido fluye hacia abajo en un dispositivo cilíndrico y aire seco a 300 K y $1.013 \times 10^5$ Pa fluye en ángulos rectos donde el equipo tiene un diámetro de 0.076 m y 1.22 m de longitud vertical a una velocidad de 4.6 m/s. Si la temperatura de la película líquida es de 290 K calcular la velocidad a la cual el líquido deber ser rellenado en el depósito para continuar el proceso, $\rho_{aire} = 1.1769 \text{ Kg/m}^3$; $v_{aire} = 1.5689 \times 10^{-5} \text{ m}^2/\text{s}$ a 298 K y 1 atm ; $D_{AB} = 2.6 \times 10^{-5} \text{ m}^2/\text{s}$ a 298 K y 1 atm ; P.M.$_{aire} = 29 \text{ Kg/Kg}_{\text{mol}}$ y P.M.$_{agua} = 18 \text{ Kg/Kg}_{\text{mol}}$ ; la presión de vapor del agua a 290 K es $1.73 \times 10^3$ Pa donde la presión parcial del aire seco $P_{A,\infty}$ es cero.
