0.276 x 15′ x (4″)2 = 0.276 x 15 x 16 = 66 lbs of material drag. To calculate seal drag, use this equation: 3 lbs/ft of board x 2 boards x board length of 15 feet = 90 lbs of seal drag. The total of these frictions equals 156 lbs. 66 lbs + 90 lbs = 156 lbs. Assume, in this example, that belt speed = 600 feet per minute.
