Question

QUESTION 13 What should be the travel speed of a sprayer if each nozzle tip on a boom with 60 nozzles on 20-inch spacing delivers on average 0.53 gpm at 70 psi and you want to deliver 8 gpa? express in mph to one decimal place

Answer 1

we have the travel speed of a sprayer, s as,

S = PAP

where, Qn is the nozzle discharge in GPM

dn is the nozzle spacing in inches

Vs is the spray volume in GPA

Therefore,

S = 5940 x 0.53 20 X 8 - = 19.676mph

The travel speed of a sprayer should be 19.7 mph, for the given problem.
