This formula uses 4 Variables
Variables Used
Coefficient of Steadiness - The coefficient of steadiness is the reciprocal of the coefficient of fluctuation of speed.
Mean Speed in RPM - (Measured in Hertz) - Mean Speed in RPM is an average of individual vehicle speeds.
Maximum Speed in r.p.m. during Cycle - (Measured in Hertz) - Maximum Speed in r.p.m. during Cycle is the number of revolutions the drive shaft of your car is making per minute.
Minimum Speed in r.p.m. during Cycle - (Measured in Hertz) - Minimum Speed in r.p.m. during Cycle is the number of revolutions the drive shaft of your car is making per minute.
STEP 1: Convert Input(s) to Base Unit
Mean Speed in RPM: 16 Revolution per Minute --> 0.266666666666667 Hertz (Check conversion here)
Maximum Speed in r.p.m. during Cycle: 22 Revolution per Minute --> 0.366666666666667 Hertz (Check conversion here)
Minimum Speed in r.p.m. during Cycle: 10 Revolution per Minute --> 0.166666666666667 Hertz (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Msteadiness = N/(N1-N2) --> 0.266666666666667/(0.366666666666667-0.166666666666667)
Evaluating ... ...
Msteadiness = 1.33333333333334
STEP 3: Convert Result to Output's Unit
1.33333333333334 --> No Conversion Required
FINAL ANSWER
1.33333333333334 1.333333 <-- Coefficient of Steadiness
