Follow our step by step solution on how to calculate Wahl Factor for Engine Valve Spring given Mean Coil Diameter and Wire Diameter?

FIRST Step Consider the formula

K = \frac{π \cdot f s \cdot {d w}^{2}}{8 \cdot C \cdot P}

Next Step Substitute values of Variables

∴

K = \frac{π \cdot 300N/mm² \cdot {5.5mm}^{2}}{8 \cdot 8 \cdot 340N}

Next Step Substitute values of Constants

∴

K = \frac{3.1416 \cdot 300N/mm² \cdot {5.5mm}^{2}}{8 \cdot 8 \cdot 340N}

Next Step Convert Units

∴

K = \frac{3.1416 \cdot 3E+8Pa \cdot {0.0055m}^{2}}{8 \cdot 8 \cdot 340N}

Next Step Prepare to Evaluate

∴

K = \frac{3.1416 \cdot 3E+8 \cdot {0.0055}^{2}}{8 \cdot 8 \cdot 340}

Next Step Evaluate

∴

K = 1.31020006118232

LAST Step Rounding Answer

∴

K = 1.3102
