84 REPORT NATIONAL ADVISORY COMMITTEE FOR AERONAUTICS RESULTS AND DISCUSSION Good results were also obtained when methods (2) and (3) were used to obtain good spray distribution. Sprays from plain round-orifice nozzles.—Figure 3 (References 15 and 16.) Regarding the use of orderly shows the spray… … Injection pressure. Ib.per sq.in. hind the nozzle to be affected slightly for the range of orifices between 0.008 and 0.030 inch, but to be re- duced considerably for the 0.040-inch orifice. Orifice diameter = 0.030 inch. In Figure 4 the penetrations 0.002 and 0.004 second after the start of…
