RPM/Surface Speed  Nonwoven Tools
The surface speed for the same rpm jumps to 18,850 inches per minute which is 1,570 feet per minute. Notice that the diameter of the large roll is 6 times the diameter of the first roll and the surface speed is 6 times that of the first roll. We say that the surface speed varies directly as the diameter if the rotation speed or rpm stays constant.
