Here is how the Projected Length equation looks like.

40.8 = {(102 \cdot 16.32)}^{0.5}

40.8mm = {(102mm \cdot 16.32mm)}^{0.5}

40.8 = {(102 \cdot 16.32)}^{0.5}

Projected Length Solution

Follow our step by step solution on how to calculate Projected Length?

FIRST Step Consider the formula

L = {(R \cdot Δt)}^{0.5}

Next Step Substitute values of Variables

∴

L = {(102mm \cdot 16.32mm)}^{0.5}

Next Step Convert Units

∴

L = {(0.102m \cdot 0.0163m)}^{0.5}

Next Step Prepare to Evaluate

∴

L = {(0.102 \cdot 0.0163)}^{0.5}

Next Step Evaluate

∴

L = 0.0408m

LAST Step Convert to Output's Unit

∴

L = 40.8mm

How to Evaluate Projected Length?

Projected Length evaluator uses Projected Length = (Roller Radius*Change in Thickness)^0.5 to evaluate the Projected Length, projected length typically refers to the length of the material being rolled as it contacts the rolls. This length is projected onto a plane perpendicular to the direction of rolling. Projected Length is denoted by L symbol.

How to evaluate Projected Length using this online evaluator? To use this online evaluator for Projected Length, enter Roller Radius (R) & Change in Thickness (Δt) and hit the calculate button.

FAQs on Projected Length

What is the formula to find Projected Length?

The formula of Projected Length is expressed as Projected Length = (Roller Radius*Change in Thickness)^0.5. Here is an example- 40800 = (0.102*0.01632)^0.5.

How to calculate Projected Length?

With Roller Radius (R) & Change in Thickness (Δt) we can find Projected Length using the formula - Projected Length = (Roller Radius*Change in Thickness)^0.5.

Can the Projected Length be negative?

No, the Projected Length, measured in Length cannot be negative.

Which unit is used to measure Projected Length?

Projected Length is usually measured using the Millimeter[mm] for Length. Meter[mm], Kilometer[mm], Decimeter[mm] are the few other units in which Projected Length can be measured.
