For a roll of radius R, the entering and exiting material thickness is h1 and h2 respectively. What will be the total arc of contact between roll and material? Δh=h1-h2

For a roll of radius R, the entering and exiting material thickness is h1 and h2 respectively. What will be the total arc of contact between roll and material? Δh=h1-h2 Correct Answer √(RΔh)

The total contact length is defined as the square root of multiplication of roll radius with the change in the height of the rolling material. -> 1/2
