Hatta number

The Hatta number was developed by Shirôji Hatta, who taught at Tohoku University. [S. Hatta, Technological Reports of Tôhoku University, 10, 613-622 (1932).] It is a dimensionless parameter that compares the rate of absorption of a solute, A, in a reactive system (N_A0) to the rate of absorption of the same solute A in the case of physical absorption (N_A0^phys). [R.B. Bird, W.E. Stewart, E.N. Lightfoot, Transport Phenomena, 2nd ed. John Wiley & Sons, 2002.]

$Ha\; =\; frac\{N\_\{A0\{N\_\{A0\}^\{phys$
