Initial Stock Thickness given Pressure on Rolls Solution

Follow our step by step solution on how to calculate Initial Stock Thickness given Pressure on Rolls?

FIRST Step Consider the formula

h t = \frac{S \cdot h s \cdot \exp (μ f \cdot (H i - H r))}{P}

Next Step Substitute values of Variables

∴

h t = \frac{58730Pa \cdot 0.0031mm \cdot \exp (0.4 \cdot (3.36 - 3.18))}{0.0002N/mm²}

Next Step Convert Units

∴

h t = \frac{58730Pa \cdot 3.1E-6m \cdot \exp (0.4 \cdot (3.36 - 3.18))}{189Pa}

Next Step Prepare to Evaluate

∴

h t = \frac{58730 \cdot 3.1E-6 \cdot \exp (0.4 \cdot (3.36 - 3.18))}{189}

Next Step Evaluate

∴

h t = 0.00104715925466843m

Next Step Convert to Output's Unit

∴

h t = 1.04715925466843mm

LAST Step Rounding Answer

∴

h t = 1.0472mm
