Brake Power of Engine for Prony Brake Dynamometer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Power = (Weight at Outer End of Lever*Distance between Weight and Center of Pulley*2*pi*Speed of Shaft in RPM)/60
BP = (W_e*L_h*2*pi*N)/60
This formula uses 1 Constants, 4 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.
Weight at Outer End of Lever - (Measured in Newton) - Weight at outer end of lever is the force acting on the object due to gravity.
Distance between Weight and Center of Pulley - (Measured in Meter) - Distance between weight and center of pulley is a numerical measurement of how far apart objects or points are.
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

Weight at Outer End of Lever: 22.75 Newton --> 22.75 Newton No Conversion Required
Distance between Weight and Center of Pulley: 1.45 Meter --> 1.45 Meter No Conversion Required
Speed of Shaft in RPM: 500 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BP = (W_e*L_h*2*pi*N)/60 --> (22.75*1.45*2*pi*500)/60

Evaluating ... ...

BP = 1727.22146100489

STEP 3: Convert Result to Output's Unit

1727.22146100489 Watt --> No Conversion Required

FINAL ANSWER

1727.22146100489 ≈ 1727.221 Watt <-- Brake Power

(Calculation completed in 00.020 seconds)
