On the basis of the system of differential equations in 
partial derivatives, the boundary-value problem of heat and mass transfer 
under cooling of flowing water sheets by a turbulent air counterflow 
has been formulated. Its approximate analytical solution is given. 
From the point of view of the accepted model of interaction of flows, 
it has been shown that the obtained theoretical values of the heat 
and mass transfer coefficients are in good agreement with the experiment.
