• In "The Effect of Nozzle Design on the Stability and Performance of Turbulent Water Jets" (Fire Safety Journal, Vol. 4, August 1981), C. Theobald describes an experiment in which a shape measurement was determined for several different nozzle types at different levels of jet efflux velocity. Interest in this experiment focuses primarily on nozzle type, and velocity is a nuisance factor. The data are as follows: Nozzle Type Jet Efflux Velocity (m/s) JEF 11.73 JEF 14.37 JEF 16.59 JEF 20.43 JEF 23.46 JEF 28.74 1 0.78 0.8 0.81 0.75 0.77 0.78 2 0.85 0.85 0.92 0.86 0.81 0.83 3 0.93 0.92 0.95 0.89 0.89 0.83 4 1.14 0.97 0.98 0.88 0.86 0.83 5 0.97 0.86 0.78 0.76 0.76 0.75
