As 50: 48: 98 98 50)470-4 944/so teeth-wheel required. Power Of Belts. A 20 inch belt is moving at the rate of 2000 feet per minute; with 6 feet of its length in contact with the circumference of a 4 foot drum. What will be its horse power? 20 x 72 = 1410--2 = 2000 = 1,440,000 + 36,000 = 40 nominal horse power = 160 Ihp. Example reversed.--40 x 36,000 x 2 2000 x 72 = 20-in. strap. It is the safest to take 33,000 per horse power. Power Of Ropes. 5-in. circumferences 150-ft. per minute = 1 Hp. 6-in. do. 110 do. = 1 Hp. 7-in. do. 87 do. = 1 Hp.
