Studies on Discharge from Multi-Nozzle along a Straight Pipe

Abstract

In order to investigate the spray distribution from boom nozzle, the theoretical formula based upon Bernoulli's theorem was made, and the calculated values from the theoretical formula were compared with the values resulted from experiment. The results were as follows;
1. The relationship between Q_i-1 and Q_i on the discharge of nozzle is as follows (Fig. 1):
Q_i/Q_i-1=√(Ca/F)²[(Q′_i-1 Q_i-1)²(-ξ-2λl_i/d)/+2(Q′_i-1 Q_i-1)(2λl_i/d+η)-(2λl_i/d+η)]+1
2. The difference between the experimental results and the calculated results, were not large.
3. The spray capacities of all individual nozzles were almost the same.
