  • Report on the determination of the longitudinal pressure profile through six thin orifice plates mounted in the EEC 100 mm assembly using AGA tappings throughout


The longitudinal pressure profiles through the six EEC orifice plates, having nominal diameter ratios of 0.2, 0.375, 0.5, 0.57, 0.66 and 0.75, were determined. Discharge coefficients were measured simultaneously in each case over a range of ten flowrates and agreed with the 1986/87 NEL results to within 0.2%, apart from the 0.2 plate where differences of up to 0.5% were found.
