Follow our step by step solution on how to calculate Brake Power of Engine for Rope Brake Dynamometer?

FIRST Step Consider the formula

BP = \frac{(W d - S) \cdot π \cdot (D w + d r) \cdot N}{60}

Next Step Substitute values of Variables

∴

BP = \frac{(43.25N - 2N) \cdot π \cdot (1.6m + 0.001m) \cdot 500}{60}

Next Step Substitute values of Constants

∴

BP = \frac{(43.25N - 2N) \cdot 3.1416 \cdot (1.6m + 0.001m) \cdot 500}{60}

Next Step Prepare to Evaluate

∴

BP = \frac{(43.25 - 2) \cdot 3.1416 \cdot (1.6 + 0.001) \cdot 500}{60}

Next Step Evaluate

∴

BP = 1728.95588194906W

LAST Step Rounding Answer

∴

BP = 1728.9559W
