STEP 0: Pre-Calculation Summary

Formula Used

Propeller Efficiency = Thrust Power/Shaft Power
η_p = P_thrust/S_p
This formula uses 3 Variables

Variables Used

Propeller Efficiency - Propeller efficiency is defined as power produced (propeller power) divided by power applied (engine power).
Thrust Power - (Measured in Watt) - Thrust Power refers to the power generated by a propulsion system to produce thrust and propel an object forward.
Shaft Power - (Measured in Watt) - Shaft Power is the mechanical power transmitted from one rotating element of a vehicle, ship, and all types of machinery to another.

STEP 1: Convert Input(s) to Base Unit

Thrust Power: 122 Kilowatt --> 122000 Watt (Check conversion here)
Shaft Power: 130 Kilowatt --> 130000 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_p = P_thrust/S_p --> 122000/130000

Evaluating ... ...
