Fluid-flow measurements of petroleum can be performed using a variety of equipment such as orifice meters and wellhead chokes. It is useful to understand the relationship between flow rate through orifice meters (Qv) and the five fluid-flow influencing input variables: pressure (P), temperature (...
The flow rate of grains through large orificesis known to be dependent on its diameter to a 5/2 powerlaw. This relationship has been checked for big outlet sizes,whereas an empirical fitting parameter is needed to reproducethe behavior for small openings. In this work, we provideexperimental ...
With the compound wall treatment the ζ-f model predicts shorter reattachment length and higher mass transfer rate in the flow through an orifice. 展开 关键词: Flow (Dynamics Mass transfer Computational fluid dynamics Modeling 会议名称: International Conference on Nuclear Engineering & the Asme Power...
However, the mass flow-rate of the gas through such an orifice throat is generally derived from a well-known mathematical model, which is originally developed to describe the mass flow-rate through an ideal nozzle. It is reasonable to doubt if there is any difference between the property of ...
(1983) who described a decreased void fraction effect due to the orifice and are more in line with the findings by Sekoguchi (1978) and McQuillan and Whalley (1984). The latter showed that the minimum film thickness and film flow rate decrease on the downstream side of the orifice which ...
Additionally, the pressure drop of the two-stage orifice is less than that of the single orifice under the same volume flow rate. The prestage cylindrical hole slows the changing trend of the flow field parameters, and the second-stage orifice with smaller diameter is mainly responsible for the...
Flow rate through the orifice, Q liters/sec Calculate Calculation precision Digits after the decimal point: 3 Link Save Widget Flow through a small hole in a thin wall In the case of fluid flow through a hole, we are primarily interested in the flow rate of the flowing fluid. Th...
Orifice plate sizing calculator. Calculate orifice diameters and flow rate for measured pressure drop. Calculator is based on ISO 5167
‘Fully analytical flowrate prediction’ is the estimation of flowrate through a turbine from basic fluid and thermodynamic principles as a function of the turbine’s size, shape, and head. From: Comprehensive Renewable Energy, 2012 About this pageSet alert ...
A pressure type flow rate control apparatus is provided wherein flow rate of fluid passing through an orifice is computed as Qc=KP1 (where K is a proportionality constant) or
