1800 (rpm) x 9.0" (motor sheave dia) divide by 20 (screen sheave dia in inches) = 810 RPM
1800 X 9.O
= 810 RPM
20
RPM is very important and we can figure it out without the acutal TACHOMETER. (If may be different is sheaves are worn, which would make it a slower RPM)
OR................WORK the known numbers BACKWARDS:
IE: Screen speed 783 rpm x 20
= 1740 RPM (motor speed)
9 (Motor Sheave)
GOOD ONE TO PRINT for later use.......
