By means of the double Laplace<196>Carson transform as 
integral averaging of the time function decreasing by the exponential 
law with weight and along a semi-bounded pipe, the nonstationary heat 
transfer equation under steady-state laminar or turbulent flow conditions 
is transformed into a boundary-value problem, which is solved by the 
method of orthogonal projection of the residual, where, as a finite 
element, the entire boun-ded domain of variation of elliptic coordinates 
is taken.
