Discharge Coefficients of Long-Radius Flow Nozzles When Used With Pipe-Wall Pressure Taps

For the last six years, the Special Research Committee on Fluid Meters has been conducting a research on flow nozzles. In previous papers relating to the program, the Committee’s plans for carrying out the research were outlined (1), and some of the results obtained have been presented (2, 3, 4). In the present paper, the results of determinations of coefficients of long-radius nozzles when used with pipe-wall taps are given, as based on a combination of separate analyses by the three authors. Later papers will extend the results to other conditions than those considered in this paper.
