  • Progress report no. 14 on EEC orifice plate coefficients project : Addenda to progress reports nos. 2 and 7 on NEL tests in water on thin orifice plates for EEC 100 mm assembly


The 0.2 orifice plate was recalibrated in March 1984 and found to agree with the 1980 calibration made in the older NEL cold-water test facility. This confirmed that the 1983 tests in the new facility had been affected at flow rates below 3 l/s. Appendices are given showing the valid figures.
