Gas flow in pipes

WebGas Flow in Pipeline. As in calculating the incompressible flow, the gas-dynamic calculation is reduced to solving the Bernoulli equation for two successive cross-sections: P 1 + w 1 2 ρ / 2 = P 2 + w 2 2 ρ / 2 + ΔP … WebWhen some flow rate is reached, however, it is usually observed that the pressure drop gradually begins to increase more than proportionally to the flow rate. It is well known that this phenomenon was first observed by Osborne Reynolds in 1901 in experimenting with flow through pipes. In his classical experiments.
