### Notes to complete the above

Kilometres per Hour can be calculated as follows Distance in Metres x 3.6 divided by time in seconds to travel distance.

**If the above is confusing, here are the actual formula used to calculate each item.**

Kilometres per Hour (kph) = litres per minute per nozzle x 600 / litres per sprayed hectare / width (in metres)

Litres per minute per nozzle (l/min/nozz) = Litres per sprayed hectare(l/s-ha) x width (in metres) x kph / 600

Litres per sprayed hectare (l/sp/ha) = litres per minute per nozzle (l/min/nozz) x 600 / kph / width (in metres)
