Diameter of Port given Diameter of Valve Stem Solution

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

FIRST Step Consider the formula

d p = \frac{d s}{1.5 \cdot (1 - \frac{σ t \cdot t^{2}}{1.4 \cdot P s})}

Next Step Substitute values of Variables

∴

d p = \frac{15mm}{1.5 \cdot (1 - \frac{2.2N/mm² \cdot {5.5mm}^{2}}{1.4 \cdot 63N})}

Next Step Convert Units

∴

d p = \frac{0.015m}{1.5 \cdot (1 - \frac{2.2E+6Pa \cdot {0.0055m}^{2}}{1.4 \cdot 63N})}

Next Step Prepare to Evaluate

∴

d p = \frac{0.015}{1.5 \cdot (1 - \frac{2.2E+6 \cdot {0.0055}^{2}}{1.4 \cdot 63})}

Next Step Evaluate

∴

d p = 0.0407390300230947m

Next Step Convert to Output's Unit

∴

d p = 40.7390300230947mm

LAST Step Rounding Answer

∴

d p = 40.739mm
