Gas Load on Exhaust Valve when it Opens Solution

Follow our step by step solution on how to calculate Gas Load on Exhaust Valve when it Opens?

FIRST Step Consider the formula

P g = \frac{π \cdot P b \cdot {d v}^{2}}{4}

Next Step Substitute values of Variables

∴

P g = \frac{π \cdot 0.8MPa \cdot {50mm}^{2}}{4}

Next Step Substitute values of Constants

∴

P g = \frac{3.1416 \cdot 0.8MPa \cdot {50mm}^{2}}{4}

Next Step Convert Units

∴

P g = \frac{3.1416 \cdot 800000Pa \cdot {0.05m}^{2}}{4}

Next Step Prepare to Evaluate

∴

P g = \frac{3.1416 \cdot 800000 \cdot {0.05}^{2}}{4}

Next Step Evaluate

∴

P g = 1570.7963267949N

LAST Step Rounding Answer

∴

P g = 1570.7963N
