Nozzle Coefficients for Free and Submerged Discharge Available to Purchase

This paper presents in brief form a summary of investigations made at the hydraulic laboratory of the University of California, in cooperation with the A.S.M.E. Special Research Committee on Fluid Meters, to determine nozzle coefficients for free and submerged discharge. A description of test facilities and procedure is included. The results given concern a series of A.S.M.E. long-radius nozzles for 3-in., 4-in., and 8-in. pipes tested with pipes of different wall roughness, various upstream piping arrangements, and different pressure-tap locations. Some data on I.S.A. nozzles which have been manufactured at the University shops are added.
