Coefficient of Discharge of the Nozzle for Power-driven Sprayer

Abstract

1. Since the coefficient of discharge of the orifice is the function of Reynolds number, the author expected that this relation may be realized in the nozzle for sprayer and with respect to one of nozzles the author investigated the relation tune between the coefficient of discharge and Reynolds number by means of experiments. This curve can be applied to liquids having different viscosities by Reynolds' law of similarity.
2. The results of the experiments showed that the coefficient of discharge is 0.389-0.312 in case where Reynolds number is 0.8×10⁴-3.3×10⁴ and the author found that the coefficient decreases with increase of Reynolds number.
