An approximate method for the calculation of heat and mass exchange between gas and a liquid film

Using integral relations between the velocity and enthalpy of gas, we develop an engineering method for the calculation of the local and average parameters of media and the heat and mass flux without using the empirical data about contact instruments.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 53, No. 2, pp. 191–198, August, 1987.
