The exact forward speed can also be calculated using the following formula:
Example : You need 45 seconds for 100 m:
Determining the nominal output quantity per minute
To calculate the nominal output quantity per minute, you will require the following:

The exact forward speed,

the working width,

the desired application rate.
Example : You wish to calculate the nominal output quantity at a particular outlet.
Your forward speed is 8 km/h , the working width is specified to be 18 m and the
application rate shall amount to 300 kg/ha .
Calculation with the calibration test calculator:
1.
Move the tab until it is at 300 kg/ha under 18 m.
2. The value of the nominal output quantity for both outlets can now be read off
above the value of the forward speed of 8 km/h.
 The nominal output quantity per minute amounts to 72 kg/min.
If you implement the calibration at one output only, halve the total value of the
nominal output quantity.
3. Divide the read off value by 2 (= number of outlets).
 The nominal output quantity per output amounts to 36 kg/min.
Forward speed (km/h) =
360
Stopped time on 100m

NOTICE
For some application rates and forward speeds, the output quantity is already
shown in the fertiliser chart.
If you cannot find your values in the fertiliser chart, they can be determined with
the calibration test calculator or with a formula.
