Why should the velocity through the nozzle throat be sonic?

WebTechnical Background. The 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. WebOct 31, 2024 · This principle can be expressed mathematically as: Where: m 1 = mass flow rate at the inlet of the pipe (kg/s) m 2 = mass flow rate at the outlet of the orifice plate (kg/s) ρ 1 = density of fluid at the inlet of the pipe (kg/m 3) ρ 2 = density of fluid at the outlet of the orifice plate (kg/m 3) V 1 = flow velocity at the inlet of the pipe (m/s) green education postersWebMar 8, 2024 · Outlook.
