WebA converging-diverging nozzle is attached via a valve to a pipe holding compressed air at 1.00 MPa and 20.0°C. The valve is opened and the air passes through the nozzle and into the atmosphere. Assuming isentropic flow throughout, determine a. The exit Mach number. b. The exit temperature. c. The exit velocity. d. Web# Nozzle Choking: Fluid flow through a restricted area whose rate reaches a maximum when the fluid velocity reaches the sonic velocity at some point along the flow path. The phenomenon of choking exists only in compressible flow and can occur in several flow situations. Through Varying-Area Duct
Choked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. Choked flow is a fluid dynamic condition associated with the venturi effect. When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent-divergent nozzle or a valve in a pipe) into a lower pressure environment the fluid velocity increase…
