Radial Width of Piston Ring Solution

Follow our step by step solution on how to calculate Radial Width of Piston Ring?

FIRST Step Consider the formula

b = D i \cdot \sqrt{3 \cdot \frac{p w}{σ tp}}

Next Step Substitute values of Variables

∴

b = 180mm \cdot \sqrt{3 \cdot \frac{0.025N/mm²}{85N/mm²}}

Next Step Convert Units

∴

b = 0.18m \cdot \sqrt{3 \cdot \frac{25000Pa}{8.5E+7Pa}}

Next Step Prepare to Evaluate

∴

b = 0.18 \cdot \sqrt{3 \cdot \frac{25000}{8.5E+7}}

Next Step Evaluate

∴

b = 0.00534679673207404m

Next Step Convert to Output's Unit

∴

b = 5.34679673207404mm

LAST Step Rounding Answer

∴

b = 5.3468mm
