Projected Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Projected Length = (Roller Radius*Change in Thickness)^0.5
L = (R*Δt)^0.5
This formula uses 3 Variables

Variables Used

Projected Length - (Measured in Meter) - Projected Length of an object is a length for which the roller is in contact with the material.
Roller Radius - (Measured in Meter) - The Roller Radius is the distance between the center and the point on the circumference of the roller.
Change in Thickness - (Measured in Meter) - Change in Thickness can be defined as the difference between final and initial thickness of the workpiece being rolled.

STEP 1: Convert Input(s) to Base Unit

Roller Radius: 102 Millimeter --> 0.102 Meter (Check conversion here)
Change in Thickness: 16.32 Millimeter --> 0.01632 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L = (R*Δt)^0.5 --> (0.102*0.01632)^0.5

Evaluating ... ...

L = 0.0408

STEP 3: Convert Result to Output's Unit

0.0408 Meter -->40.8 Millimeter (Check conversion here)

FINAL ANSWER

40.8 Millimeter <-- Projected Length

(Calculation completed in 00.004 seconds)

How to Calculate Projected Length or Roll contact length?

Projected length is also known as Roll contact Length. It is the length of stock in contact with the roller projected on the roller surface. It can be calculated by taking into account the radius of roller and change in thickness.

How to Calculate Projected Length?

Projected Length calculator uses Projected Length = (Roller Radius*Change in Thickness)^0.5 to calculate 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 calculate Projected Length using this online calculator? To use this online calculator for Projected Length, enter Roller Radius (R) & Change in Thickness (Δt) and hit the calculate button. Here is how the Projected Length calculation can be explained with given input values -> 40800 = (0.102*0.01632)^0.5.

FAQ

What is 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 and is represented as L = (R*Δt)^0.5 or Projected Length = (Roller Radius*Change in Thickness)^0.5. The Roller Radius is the distance between the center and the point on the circumference of the roller & Change in Thickness can be defined as the difference between final and initial thickness of the workpiece being rolled.

How to calculate 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 is calculated using Projected Length = (Roller Radius*Change in Thickness)^0.5. To calculate Projected Length, you need Roller Radius (R) & Change in Thickness (Δt). With our tool, you need to enter the respective value for Roller Radius & Change in Thickness and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
