Choked flow can occur at the change of the cross section in a de Laval nozzle or through an orifice plate. The choked velocity is observed upstream of an orifice or nozzle. The upstream volumetric flow rate is greater than the downstream condition because of the higher downstream density. The choked velocity is a function of the upstream pressure but not the downstream. Although the velocity is constant, th…
