Brake power measured with dynamo meter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Power = (pi*Pulley Diameter*(Engine Speed*60)*(Dead Weight-Spring Scale Reading))/60
BP = (pi*D*(N*60)*(W_d-S))/60
This formula uses 1 Constants, 5 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.
Pulley Diameter - (Measured in Meter) - Pulley Diameter is defined as the diameter of pulley of rope brake dynamo meter.
Engine Speed - (Measured in Radian per Second) - Engine Speed is the speed at which the crankshaft of the engine rotates.
Dead Weight - (Measured in Newton) - Dead Weight is the weight of the body attached to the spring balance in newtons.
Spring Scale Reading - (Measured in Newton) - Spring Scale Reading is defined as the readings shown in the spring balance after the dead weight is attached to it.

STEP 1: Convert Input(s) to Base Unit

Pulley Diameter: 0.0021 Meter --> 0.0021 Meter No Conversion Required
Engine Speed: 400 Revolution per Minute --> 41.8879020457308 Radian per Second (Check conversion here)
Dead Weight: 10 Newton --> 10 Newton No Conversion Required
Spring Scale Reading: 3 Newton --> 3 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BP = (pi*D*(N*60)*(W_d-S))/60 --> (pi*0.0021*(41.8879020457308*60)*(10-3))/60

Evaluating ... ...

BP = 1.934442462515

STEP 3: Convert Result to Output's Unit

1.934442462515 Watt --> No Conversion Required

FINAL ANSWER

1.934442462515 ≈ 1.934442 Watt <-- Brake Power

What is brake power measured with dynamo meter?

The rope dynamo meter measures the power by absorbing all the energy of the engine or prime mover by means of frictional resistance. The rope brake dynamo meter is the device that measures the power of the engine shaft by applying frictional resistance to the motion of the shaft by use of rope. It simply consists of pulley and rope arrangement along with the spring balance to measure the tension in ropes. The rope brake dynamo meter measures the torque required to stop the shaft of the prime mover.
