WebJan 19, 2024 · Pressure drop has been measured for upward single- and two-phase gas–liquid flow across an orifice in a vertical pipe. A conductance probe provided average void fraction upstream of the orifice. Six orifices with different apertures/thickness were mounted in turn in a 34 mm diameter transparent acrylic resin pipe. Gas and liquid … 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.
