WebThe usual configuration for a converging diverging (CD) nozzle is shown in the figure. Gas flows through the nozzle from a region of high pressure (usually referred to as the chamber) to one of low pressure (referred to as the ambient or tank). The chamber is usually big enough so that any flow velocities here are negligible. http://dictionary.dauntless-soft.com/definitions/groundschoolfaa/Convergent-Divergent+Duct importance of dressmaking and tailoring
