Where:
V = Ground speed in MPH
RPM = Rev. per min. of engine
C = Circumference
C = N x L
N = No. of teeth in sprocket
L = Length of links in inches
R = Overall gear reduction
Example:
Find the ground speed in miles per hour where the motor speed is 1800
RPM, the number of teeth in the sprocket is 41, the length of link 8 inches,
is 61 to 1.
C = 41 x 8 = 328
Where:
V = Ground speed in KPH
RPM = Rev. per min. of engine
C = Circumference
C = N x L
N = No. of teeth in sprocket
L = Length of links in millimetres
R = Overall gear reduction
Example:
Find the ground speed in kilometres per hour where the motor speed is
1800 RPM, the number of teeth in the sprocket is 41, the length of link
200 mm, is
61 to 1.
C = 41 x 200 = 8200
