Shock Strength Solution

Follow our step by step solution on how to calculate Shock Strength?

FIRST Step Consider the formula

Δp str = (\frac{2 \cdot γ}{1 + γ}) \cdot ({M 1}^{2} - 1)

Next Step Substitute values of Variables

∴

Δp str = (\frac{2 \cdot 1.4}{1 + 1.4}) \cdot ({1.49}^{2} - 1)

Next Step Prepare to Evaluate

∴

Δp str = (\frac{2 \cdot 1.4}{1 + 1.4}) \cdot ({1.49}^{2} - 1)

Next Step Evaluate

∴

Δp str = 1.42345

LAST Step Rounding Answer

∴

Δp str = 1.4235
