Calculating the exact forward speed
u
With a
semi-filled
machine, drive a distance of
100
m
on the field
.
u
Stop the time required for this.
u
The exact forward speed is indicated at the scale of the calibration test calculator.
Fig. 31: Scale for calculating the exact forward speed
The exact forward speed can also be calculated using the following formula:
Forward speed (km/h)
=
360
Time over 100 m
Example: You need 45 seconds for 100 m:
360
= 8 km/h
45 s
Determining the nominal output volume per minute
To calculate the nominal output volume per minute, you will require the following:
•
The exact forward speed
•
The working width
•
The desired application rate
Example:
The nominal output volume at a particular outlet is to be determined. 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.
