Spring Force on Valve when Seated Solution

Follow our step by step solution on how to calculate Spring Force on Valve when Seated?

FIRST Step Consider the formula

P s = \frac{\frac{σ t \cdot t^{2}}{1 - \frac{2 \cdot d s}{3 \cdot d p}}}{1.4}

Next Step Substitute values of Variables

∴

P s = \frac{\frac{2.2N/mm² \cdot {5.5mm}^{2}}{1 - \frac{2 \cdot 15mm}{3 \cdot 40mm}}}{1.4}

Next Step Convert Units

∴

P s = \frac{\frac{2.2E+6Pa \cdot {0.0055m}^{2}}{1 - \frac{2 \cdot 0.015m}{3 \cdot 0.04m}}}{1.4}

Next Step Prepare to Evaluate

∴

P s = \frac{\frac{2.2E+6 \cdot {0.0055}^{2}}{1 - \frac{2 \cdot 0.015}{3 \cdot 0.04}}}{1.4}

Next Step Evaluate

∴

P s = 63.3809523809524N

LAST Step Rounding Answer

∴

P s = 63.381N
