Propeller Efficiency Solution

STEP 0: Pre-Calculation Summary
Formula Used
Propeller Efficiency = Thrust Power/Shaft Power
ηp = Pthrust/Sp
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
ηp = Pthrust/Sp --> 122000/130000
Evaluating ... ...
ηp = 0.938461538461538
STEP 3: Convert Result to Output's Unit
0.938461538461538 --> No Conversion Required
FINAL ANSWER
0.938461538461538 0.938462 <-- Propeller Efficiency
