A drill had been run through the end of the nozzle to make theopening smooth, round, and of a uniform size for a short length at thetip. This nozzle is shown in Fig. i, and will be referred to hereafteras nozzle A. The second nozzle tested was the same as nozzle A, exceptthat it was bored out to remove the roughness and the opening made auniform size for a length of 1/2 n. with a i/2-in. reamer.

This last nozzle isshown in Fig. 5, a^d will be referred to hereafter as nozzle C. The pressure at the base of the nozzle was measured with Bourdongauges. In general, one gauge was used for small pressures and anotherfor higher pressures. Both gauges were calibrated with a Crosby Gauge /7<£ I. F/6. 2experimentsupond00kors
