WebJul 13, 2004 · Two issues. Irregular orifices can be dealt with on the basis of an hydraulic radius (i.e. an effective flow area) regardless of the shape. This is approximate. As far as the flow through your 0.7" slot, you know the area and you either know the pressure drop or you can estimate the fluid velocity. Either way you can come up with a flow estimate. Webdetermine the mass flow rate in the annular passage. At the outer tube wall, the stream function value is specified as zero (~O o = 0). At the inner tube wall, the stream function value is I]/i ~--- (1 - r2)/2 (4) which corresponds to the volume flow rate in an annulus with

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. WebFlow metering has undergone major evolution over the last seven decades, from the use of differential pressure (DP) flow meters – at their simplest using an orifice plate or flow …
