On this slide we derive the equations which explain and describe why a supersonic flow accelerates in the divergent section of the nozzle while a subsonic flow decelerates in a divergent duct. See G27 Park Toolhead for details. The engine pressure ratio (EPR) is defined to be the total pressure ratio across the engine. The effect of inlet guide vanes is shown in Fig. Types of Nozzles: 1. Because the exit velocity is greater than the free stream velocity, thrust is created as described by the thrust equation. And we can set the exit Mach number by setting the area ratio of the exit to the throat. A pitot tube is used to measure fluid flow velocity. Airsoft is a recreational sport for guns enthusiast. The smallest cross-sectional area of the nozzle is called the throat of the nozzle. The tube is pointed into the flow and the difference between the stagnation pressure at the tip of the probe and the static pressure at its side is measured, yielding the dynamic pressure from which the fluid velocity is calculated using Bernoulli's equation.A volumetric rate of flow may be determined by measuring the velocity at Usage velocity is reduced to 0. Animated Intake Stroke Note that C 2 is independent of p 2 and that the nozzle flow is a maximum.
