Why Does Flow Become Supersonic in the Diverging Section of a Nozzle? i just started reading about nozzles and turbines in my semester course i went through converging diverging nozzles for achieving a supersonic flow, a converging diverging nozzle is used now a converging section will work as a nozzle only till the flow is subsonic and a diffuser at supersonic
Supersonic Flow in Diverging Nozzle - Physics Forums Clearly, at low speeds the velocity of a fluid increases when the area through which it is traveling decreases I am curious as to why a fluid traveling faster than the speed of sound increases its velocity when its area is increased Thank you
Identifying Converging and Diverging Lenses: Explaining with Principal . . . To determine whether a lens is converging or diverging, analyze the behavior of the principal rays after they pass through the lens A convex lens will cause rays to converge at a point on the opposite side, while a concave lens will cause rays to diverge, appearing to originate from a point on the same side as the object Drawing the three principal rays—one through the center, one parallel
Is there a pressure ratio limit for choked flow through a c-d nozzle . . . Is there a point at which the angle is too great, and the diverging part is no longer effective, and the flow goes back to behaving like only having a converging section? It seems there must be a limit otherwise choked flow could be achieved with only a very slight pressure difference
How Do You Calculate Image Distance and Height Using Lenses? To calculate image distance and height using lenses, a converging lens with a focal length of 50 cm and a diverging lens with a focal length of -52 cm are positioned 227 cm apart The distance between the image and the diverging lens is determined to be 26 cm The image height is calculated to be 4 9 cm, although there was confusion regarding the sign convention for magnification, with
Real Object, Images formed by a single converging or diverging lens . . . A discussion on the formation of images by single lenses highlights key truths about converging and diverging lenses A converging lens can create a virtual, upright, enlarged image when the object is placed between the focal point and the lens, while it cannot produce a real, inverted, reduced image
Is it possible to have a Mach number greater than 1 at the throat? The discussion centers on whether a Mach number greater than 1 can occur at the throat of a converging-diverging nozzle Initially, it is asserted that the Mach number at the throat must equal 1, as flow cannot accelerate beyond this point in a converging section However, it is clarified that if the inlet Mach number is supersonic, the throat can indeed exhibit a Mach number greater than 1
Why Do Diverging Lenses Always Produce Shrunken Images? I also read that no matter where the object is with respect to a diverging lense the image formed will always be shrunken and inverted Why would the object be shrunken if the device disperses rays?
Optical System with Diverging Lens and Concave Mirror Homework Statement A diverging thin lens and a concave mirror have focal lengths of equal magnitude An object is placed (3 2)f from the diverging lens and the mirror is placed a distance 3f on the other side of the lens Using Gaussian optics, determine the final image of the system after two
Object 18cm in Front of Lens to Reduce Image by 2. 0 An object placed 18cm in front of a diverging lens with a focal length of -12cm needs to be repositioned to achieve a reduced image size by a factor of 2 0 Initial calculations yield an image distance of 7 2cm, leading to a magnification of -0 4 However, to find the correct object distance for the desired magnification, the equation must be adjusted to account for the new conditions
