89 belt tension calculations w b =weight of belt in pounds per foot of belt length. when the exact weight of the belt is not known, use average estimated belt weight (see table 6-1) w m =weight of material, lbs per foot of belt length: three multiplying factors, k t , k x , and k y , are used in calculations of three of the components of the effective belt tension, t
measurement system. imperial. metric. belt speed (ft/minm/s) capacity (tons/hour) total belt weight (lbskg) total weight of rotating parts (lbskg) h - elevation change (ftm) l - conveyor length (ftm)
you'll need to know the weight of the conveyor belt components, or cw, the belt length, or l, and the friction factor for normal empty belt operation, or f1. f1 is normally 0.035, and the formula for calculating tc is tc = f1 x l x cw or tc = 0.035 x l x cw.

from formula (7) l = 13,817 = 658 feet 0.25 (42) (2) 3. sample calculation: determine the estimated force needed and length of 36-inch rpm pipe that can be pushed/pulled through a dry 42-inch rcp. the axial compressive stress of the rpm pipe is 14,000 psi. the pipe stiffness is 36 psi having a wall thickness of 0.72 inches.
calculates the rolled length of a roll of material when the outside diameter of the material, thickness of the material, and the diameter of the hole in the center or the tube on which the material is wound are given. variations due to stretching or softness of the material are to be ignored.
belt length. the length of the belt can be calculated as. lb = (dm π / 2) + (df π / 2) + (2 lfm) + ( (df - dm)2 / (4 lfm)) (1) where. lb = length of belt (mm, inches) df = pulley (sheave) diameter fan (mm, inches) dm = pulley (sheave) diameter motor (mm, inches) π = 3.14..
volume of bricks with mortar. volume of 1 brick with mortar = 200 x 100 x 100 ( 10 mm mortar thickness on all sides) = 0.2 x 0.1 x 0.1. volume of brick with mortar = 0.002 cum (m3) therefore, number of bricks required for 1 cubic metre = 1/0.002 = 500 no.s.
concrete calculator our concrete calculator allows you to accurately work out the amount of concrete you'll need for your project. simply add the measurements for your concrete order to the relevant shapes above (you only have to fill in the shape/s you want to use) you can build up a concrete calculation for complicated areas by adding additional shapes of each type.
diameter of 40 mm, shaft length of 292 mm and electric motor power of 3 hp. design consideration of this paper is to calculate mixing force, mixing value, belt tension and required power by mixer. the result obtained show the mixing force of 1471.5 n, mixing volume of 0.348 m 3 and required power by mixture of 2.43 hp. mix the components.
i am assuming that you mean 'how do you caculate the length of belt in a roll?' and not how much belt is around a pulley. i use these formulas: when thickness of the belt is known: l = ((d*d)-(c*c)) / (15.3*t) l = length; d = outside diameter (inches); c = inside diameter (inches); t = belt thickness (inches) when wraps are known: l = ((d+c)*3.14*n) / 24
lap splice length in a footing lap length for concrete of 1:2:4 nominal mix: the lapping length in tension (ms bar – mild steel bar) including anchorage value is 58d. so eliminating the anchorage value, the lap length = 58d – 2*9d = 40d. (where 9d = hook allowance up to 25 mm and k=2) lap length for m20 concrete: columns – 45d; beams – 60d

we can input these figures into our equation as d = 500, d = 100, and t = 0.5, and we will thereby find the length: π × (d 2 / 4 − d 2 / 4) / t = l = π × (500 2 / 4 − 100 2 / 4) / 0.5

this can be achieved from design drawings. after that, the following steps will be taken to compute steel quantity. calculate the required number of bars for both directions. no. of bars = { (l or w – concrete cover for both sides) ÷ spacing} +1 equation 8 where l or w: length or width of footing. then, find the length of one bar.
for the outrigger pad calculator to work effectively you'll need maximum load per outrigger and the maximum allowable ground pressure in the same unit of measurement. don't worry, if you don't know the ground pressure - the calculator will ask you for the surface materials and you'll be able to select the most appropriate type.
crane configuration – radius: 12m – boom length: 32.4m (crane can lift 4.5 tons) crane utilisation load 4t x 100 ÷ 4.5 = 88.8% crane utilization too high for hazardous area (chemical plant) you would need to reduce boom length or reduce crane radius load 4t (@10m) x 100 ÷
