Abstract
The article discusses the question of the effect of nonuniformity of the parameters, brought about by the two-dimensional character of the flow on the value of the specific momentum of the flow under supercritical conditions. It is shown, that, in the approximation of an ideal (nonviscous and non-heat-conducting) gas, the corresponding value with a continuous flow always exceeds the value calculated in accordance with the one-dimensional theory for the same nozzle and the same stagnation parameters of the gas.
