Towing Force Calculator
Enter the values of bollard pull force, BF(kN) and engine efficiency factor, EF to determine the value of Towing Force, TF(kN).
Towing Force Formula
Towing force is crucial in determining the total force applied when pulling a vessel or vehicle, considering the bollard pull force and the efficiency of the towing system or propulsion.
Towing Force, TF(kN) in kiloNewtons is calculated by multiplying the bollard pull force, BF(kN) in kiloNewtons, with the engine efficiency factor, EF (dimensionless).
Towing Force, TF(kN) = BF(kN) * EF
TF(kN) = towing Forcein kiloNewtons, kN.
BF(kN) = bollard pull force in kiloNewtons, kN.
EF = efficiency factor.
Towing Force Calculation:
- The bollard pull force of the tugboat is 30 kN, and the efficiency factor of the towing setup is 0.85.
Given: BF(kN) = 30kN, EF = 0.85.
Towing Force, TF(kN) = BF(kN) * EF
TF(kN) = 30 * 0.85
TF(kN) = 25.5kN.
- The bollard pull force is estimated at 10 kN, and the towing force is 9kN, find efficiency factor due to various conditions.
Given: BF(kN) = 10kN, TF(kN) = 9kN.
Towing Force, TF(kN) = BF(kN) * EF
EF = TF(kN) / BF(kN)
EF = 9 / 10
EF = 0.9.
