Answer:
358.52 m/s
Explanation:
From the information given:
The required amount you should catch per nozzle in 15 secs. can be determined by using the formula:
[tex]Gallons/Min = \dfrac{(Gallons/Acre \times Miles/Hour \times nozzle \ spacing )}{5940}[/tex]
where;
Gallons/Acre = 25 GPA
[tex]= \dfrac{(25 \times 4.5 \times 60 \times \dfrac{12}{ 36})}{5940} \times \dfrac{15}{60}[/tex]
[tex]= \dfrac{(25 \times 4.5 \times 60 \times0.333)}{5940} \times 0.25[/tex]
[tex]= \dfrac{(2247.75)}{5940} \times 0.25[/tex]
= 0.0946 gps
= 358.52 m/s
