Shaft Brake Power for Reciprocating Engine-Propeller Combination Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Power = Available Power/Propeller Efficiency
BP = P_A/η
This formula uses 3 Variables

Variables Used

Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.
Available Power - (Measured in Watt) - Available Power is the power of the engine. It is a characteristic of the power plant and written in the manufacturer specifications of the engine.
Propeller Efficiency - Propeller Efficiency is defined as power produced (propeller power) divided by power applied (engine power).

STEP 1: Convert Input(s) to Base Unit

Available Power: 20.656 Watt --> 20.656 Watt No Conversion Required
Propeller Efficiency: 0.93 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BP = P_A/η --> 20.656/0.93

Evaluating ... ...

BP = 22.210752688172
