Question

What will be the diameter of base of a spray cone in a boom sprayer?

(a) D = 2h tan \(\frac{θ}{2} \)

(b) D = 2h/tan \(\frac{θ}{2} \)

(c) D = 2h + tan \(\frac{θ}{2} \)

(d) D = 2h – tan \(\frac{θ}{2} \)

The question was posed to me in my homework.

Query is from Plant Protection Equipments topic in portion Plant Protection Equipments of Farm Machinery

Answer 1

Correct choice is (a) D = 2h tan \(\frac{θ}{2} \)

Explanation: A boom sprayer is a pipe with attached nozzles for distributing spray from a tank.

For overlapping of spray cone

Case 1: If height is given

S = (1-O) D

Case 2: If height is not given

D = (1+O) S
