Brake Mean Effective Pressure of 4S Engines given Brake power Solution

Follow our step by step solution on how to calculate Brake Mean Effective Pressure of 4S Engines given Brake power?

FIRST Step Consider the formula

P mb = \frac{2 \cdot BP}{L \cdot A c \cdot (N)}

Next Step Substitute values of Variables

∴

P mb = \frac{2 \cdot 1.93W}{8.8cm \cdot 30cm² \cdot (400rev/min)}

Next Step Convert Units

∴

P mb = \frac{2 \cdot 1.93W}{0.088m \cdot 0.003m² \cdot (41.8879rad/s)}

Next Step Prepare to Evaluate

∴

P mb = \frac{2 \cdot 1.93}{0.088 \cdot 0.003 \cdot (41.8879)}

Next Step Evaluate

∴

P mb = 349.055727480682Pa

LAST Step Rounding Answer

∴

P mb = 349.0557Pa
