Minimum Thickness of Shell at Bottom Solution

Follow our step by step solution on how to calculate Minimum Thickness of Shell at Bottom?

FIRST Step Consider the formula

t minimum = (\frac{p hydrostatic \cdot D}{2 \cdot f \cdot J}) + c

Next Step Substitute values of Variables

∴

t minimum = (\frac{0.08N/mm² \cdot 3000mm}{2 \cdot 95N/mm² \cdot 0.85}) + 10.5mm

Next Step Convert Units

∴

t minimum = (\frac{80000Pa \cdot 3m}{2 \cdot 9.5E+7Pa \cdot 0.85}) + 0.0105m

Next Step Prepare to Evaluate

∴

t minimum = (\frac{80000 \cdot 3}{2 \cdot 9.5E+7 \cdot 0.85}) + 0.0105

Next Step Evaluate

∴

t minimum = 0.0119860681114551m

Next Step Convert to Output's Unit

∴

t minimum = 11.9860681114551mm

LAST Step Rounding Answer

∴

t minimum = 11.9861mm
