APPLICATION FORMULA:
Max. torque in lb. in. = Max. roll dia. ttl. web tension
 2
Min. torque in lb. in. = Core O.D. x min. ttl. web tension
 2
Max. brake RPM = 3.82 x web speed (FPM)
 Core O.D.
Min. brake RPM = 3.82 x web speed (FPM)
 Max. roll dia.
Brake horse power = Max. ttl tension x web speed (FPM)
 33,000
Effective cooling speed = ((2 x min. RPM) + max. RPM)
