How is Power Calculated?
Power Calculation
XBoat calculates power as the amount of force applied by the hands to the oar, multiplied by the distance it travels (arc length), per second.
The calculation assumes the force is applied some distance from the tip of the handle (PositionOfForce) and is accomplished in 4 mathematical steps:
Step 1: Calculate Effective Inboard Length
EffectiveInboardLength (m) = OarInboard + (OarlockWidth / 2) - PositionOfForceStep 2: Calculate Handle Arc Length
ArcDistance (m) = 2 * π * EffectiveInboardLength * (StrokeArcLength / 360) Step 3: Calculate Work
Work (j) = Force (n) * ArcDistanceStep 4: Calculate Power
Power (w) = Work (j) / StrokeTime (s)
