From the viewpoint of the laminar boundary layer theory, 
by the method of internal and external asymptotic expansions the self-similar 
problem on the development of a plane free-convective jet at a quadratic 
temperature dependence of the density has been solved. Analytical 
dependences of the main characteristics of the jet flow on the Prandtl 
number, convenient for engineering calculations, have been obtained.
