Intake air mass of engine cylinder Solution

Follow our step by step solution on how to calculate Intake air mass of engine cylinder?

FIRST Step Consider the formula

m a = \frac{m af \cdot n R}{E rpm}

Next Step Substitute values of Variables

∴

m a = \frac{0.9kg/s \cdot 2}{5000rev/min}

Next Step Convert Units

∴

m a = \frac{0.9kg/s \cdot 2}{523.5988rad/s}

Next Step Prepare to Evaluate

∴

m a = \frac{0.9 \cdot 2}{523.5988}

Next Step Evaluate

∴

m a = 0.00343774677096kg

LAST Step Rounding Answer

∴

m a = 0.0034kg
