Abstract

In this paper the authors tell of work done in the calibration of orifices and a nozzle in a six-inch pipe line using water and steam as the fluids to be metered. Two series of orifices were tested. One series included concentric orifices with from 15 per cent to 84 per cent diameter ratio. The second series included concentric orifices with from 64 per cent to 87 per cent diameter ratio. The nozzle tested was a one-flow type with 58 per cent diameter ratio.
