The solution of problem on distribution of static pressure in the real gas stream along the pipe flow element is for the first time achieved. The solution is obtained on a basis of consideration of contact interaction of the real fluid – gas and liquid – stream with the pipe wall. Physically adequate and mathematically correct expressions for the static pressure distribution are obtained by means of use of three fundamental laws in fluid dynamics: Torricelli formula, Bernoulli equation and Weissbach-Darcy formula. General solution is obtained for the gas stream.
Special case of the obtained general solution is derived for the liquid stream.
