Flow through an annular orifice
WebVenturi flow meters, like all other types of differential pressure flow meters, function on the principles of the Bernoulli equation, which states that as the speed of the flow of a fluid increases, pressure loss occurs. Venturi tubes are available in sizes up to 72” and can pass 25 to 50% more flow than an orifice with the same pressure drop. WebPiping Design. Valves and Orifices. Cv & Kvs Values.

These relationships all utilise the parameter \beta β, the ratio of orifice … WebIn deducing this expression, it was assumed that C d for an annular orifice is approximately equal to C d for a basic orifice. ... Compressible fluids expand as they flow through a restriction (orifice plate). For practical orifice flowmeter applications, it is assumed that the expansion follows a polytropic, ideal, one-dimensional path. ...
WebThe flow rate of a known orifice is typed into the computer and timed as the water rises from the lower photocell to the higher photocell. The known flow rate multiplied by time gives a volume. In subsequent flow calibration tests this volume is divided by computer measured time and converted into a rated flow and orifice diameter. 2. WebSep 28, 2007 · A theoretical investigation has been made of core-annular flow: the flow of a high-viscosity liquid core surrounded by a low-viscosity liquid annular layer through a horizontal pipe. Special attention is paid to the question of how the buoyancy force on the core, caused by a density difference between the core and the annular layer, is …
