In an absorption tower, ammonia is absorbed from air at atmospheric pressure by acetic acid. The flowrate of 2 kg/m2s in a test corresponds to a Reynolds number of 5100 and hence a friction factor R/ρu2 of 0.020. At the temperature of absorption the viscosity of the gas stream is 0.018 mNs/m2, the density is 1.154 kg/m3 and the diffusion coefficient of ammonia in air is 1.96 × 10−5 m2/s. Determine the mass transfer coefficient through the gas film in kg/m2s (kN/m2) Explain briefly .

Question
In an absorption tower, ammonia is absorbed from air at atmospheric pressure by acetic
acid. The flowrate of 2 kg/m2s in a test corresponds to a Reynolds number of 5100 and
hence a friction factor R/ρu2 of 0.020. At the temperature of absorption the viscosity of
the gas stream is 0.018 mNs/m2, the density is 1.154 kg/m3 and the diffusion coefficient
of ammonia in air is 1.96 × 10−5 m2/s. Determine the
the gas film in kg/m2s (kN/m2)
Explain briefly .
