WebGas will always flow where there is a difference in pressure. Δp = (p 1 – p 2) > 0. The intensity of the gas flow, i.e. the quantity of gas flowing over a period of time, rises with the pressure differential. In the case of viscous flow, however, this will be the case only until the flow velocity, which also rises, reaches the speed of sound.
