question

The wet surface of a cylinder placed perpendicular to a turbulent air stream flowing with a velocity of 20 ft/sec absorbs ammonia NH_3. For this process mass transfer data is not available, But heat transfer tests conducted with same geometry and air velocity yielded a heat transfer coefficient, h = 12 Btu/hr. ft^2. °F. Determine the mass transfer coefficient h_Dfor the absorption of NH_3.
