b) How much product needs to be added to each tank?

Answer 1

Solution:-

Given data

sprayer has 20 nozzles over a boom width of 36 feet.

putput per nozzle is 365 mL per 30 seconds

It takes 22 seconds to drive 100 feet

The tank is 300 gallons

1 gallon = 3785.412 mL

1 acre = 43560 ft2

Area covered by sprayer in 22 seconds

As = 36 x 100 = 3600 ft2

time taken to cover 1 acre

= 266.2 seconds

Output of sprayer per second =

(a)

area covered with one tank

= 17.53 acres

(b)

product added to each tank

= quantity of product per acre x No. of acres

= 1 x 17.53

= 17.53 quart
