  • EEC orifice plates coefficients project : NEL air flow measurement tests undertaken on the 100 mm (4 in) orifice plate installation during phase II of the EEC orifice plate exchange test programme


Using air as the test fluid, calibrations were made on four orifice plates, 0.2, 0.57, 0.60, and 0.75, in the EEC 100 mm test section using all three tapping arrangements. Flow velocity profiles were measured immediately upstream of the orifice plate position for two different Reynolds numbers, and the friction coefficient of the pipeline was determined.
