Brake Power of Engine for Rope Brake Dynamometer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Power = ((Dead Load-Spring Balance Reading)*pi*(Diameter of Wheel+Diameter of Rope)*Speed of Shaft in RPM)/60
BP = ((W_d-S)*pi*(D_w+d_r)*N)/60
This formula uses 1 Constants, 6 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.
Dead Load - (Measured in Newton) - Dead Load includes loads that are relatively constant over time.
Spring Balance Reading - (Measured in Newton) - Spring balance Reading in newtons. The reading of the spring balance is the pulling force on it divided by the acceleration due to gravity.
Diameter of Wheel - (Measured in Meter) - The diameter of wheel is a chord that runs through the center point of the circle.
Diameter of Rope - (Measured in Meter) - The diameter of rope is a chord that runs through the center point of the circle.
Speed of Shaft in RPM - Speed of shaft in rpm is the number of turns of the shaft divided by time, specified as revolutions per minute (rpm), cycles per second (cps), radians per second (rad/s), etc.

STEP 1: Convert Input(s) to Base Unit

Dead Load: 43.25 Newton --> 43.25 Newton No Conversion Required
Spring Balance Reading: 2 Newton --> 2 Newton No Conversion Required
Diameter of Wheel: 1.6 Meter --> 1.6 Meter No Conversion Required
Diameter of Rope: 0.001 Meter --> 0.001 Meter No Conversion Required
Speed of Shaft in RPM: 500 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BP = ((W_d-S)*pi*(D_w+d_r)*N)/60 --> ((43.25-2)*pi*(1.6+0.001)*500)/60

Evaluating ... ...

BP = 1728.95588194906

STEP 3: Convert Result to Output's Unit

1728.95588194906 Watt --> No Conversion Required

FINAL ANSWER

1728.95588194906 ≈ 1728.956 Watt <-- Brake Power
