Minimum Diameter of Valve Stem Solution

Follow our step by step solution on how to calculate Minimum Diameter of Valve Stem?

FIRST Step Consider the formula

d s = \frac{d p}{8} + 6.35

Next Step Substitute values of Variables

∴

d s = \frac{40mm}{8} + 6.35

Next Step Prepare to Evaluate

∴

d s = \frac{40}{8} + 6.35

Next Step Evaluate

∴

d s = 0.01135m

LAST Step Convert to Output's Unit

∴

d s = 11.35mm
