Effect of the gas density on the force action of a turbulent jet

We have reported on the results of experimental and theoretical studies of the effect of the gas density on the force action of a gas jet for the flow parameters monitored by the pressure upstream of the outlet aperture. No appreciable effect of density has been revealed. At attempt has been made to describe the dependence of the force of action of the jet on the pressure upstream of the outlet aperture using isentropic expressions. It has been found that the only parameter of the gas that can affect the force action of the jet is the adiabatic exponent.
