Web23 aug. 2024 · Restriction orifice is mainly used to achieve pressure restriction or flow control of the process medium. Based on the service and requirements, RO should be sized for critical or pre-critical condition. Generally, pressure control RO plates are sized by considering the maximum pressure drop lesser than the critical pressure.

Webvelocity. Approximating the flow as isentropic, determine the back pressure that would result in an exit Mach number of 1.8. Solution: Assumptions: 1. Air is an ideal gas with constant specific heats. 2. Flow through the nozzle is steady, one-dimensional, and isentropic. Properties: The specific heat ratio of air is k = 1.4. WebThe sonic line and the reflected shock form a corner at their meeting point Q. This is a singularity of the boundary of the subsonic domain. This singularity is non uniform in …
WebBut by using convergent nozzle we cannot obtain super-sonic flow. 2. When the flow is super-sonic, M > 1 . i.e. for super-sonic flow, the duct must be divergent. 3. The convergent-divergent nozzle is used for convert sub-sonic flow into super-sonic flow. In the convergent part the velocity of fluid is increased from sub-sonic to sonic condition. Whenever a gas is forced through a tube, the gaseous molecules are deflected by the tube's walls. If the speed of the gas is much less than the speed of sound, the gas density will remain constant and the velocity of the flow will increase. However, as the speed of the flow approaches the speed of sound, compressibility effects on the gas are to be considered. The density of the gas becomes position dependent. While considering flow through a tube, if the flow is very graduall…

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.
