a rundown on rolling machines,machine capacity is equally if not more important than style. plate roll manufacturers commonly rate their machines according to baseline material yield strengths of 36,000 to 38,000 pounds per square inch (psi). however, you need to realize that steel mills are producing materials with ever-increasing yields..what is the formula for calculating the weight and rate of,hi guys, to calculate the weight of corrugated box or any paper board box you may use the below formula, you need to know te gsm, to get that first cut the specimen of any dimension lets say 5inches x 5inches, if it is a 3 ply or 5 ply corrugated.how to calculate the weight of steel bar?,here is the formula, formula for unit weight of steel = d 2 /162.28 kg/m. let’s take an example, if we want to calculate the unit weight of 8mm steel rod of 2-metre height, weight of steel = 8 2 /162.28 = 0.3944 kg/m * 2m = 0.79 kg. so 1- meter of 8 mm steel weighs around 0.79kg..how to calculate production capacity of a factory?,calculation of production capacity (in pieces): once you have above information use following formula to calculate production capacity. production capacity (in pieces) = (capacity in hours*60/product sam)*line efficiency. for example: suppose a factory has 8 sewing lines and each line has 25 machines..
the formula for capacity-utilization rate is actual output divided by the potential output. for example, say that a business has the capacity to produce 1,600 widgets a day as in the above example, but is only producing 1,400. the capacity utilization rate is 1,400 over 1,600, or 87.5 percent. the higher the percentage, the closer the business.how to calculate floor load capacity,determining load limits. first, determine the size, the spacing and span, and the species and lumber grade of your floor joists. look for a stamp on the joist that indicates the lumber's species and grade. use a design value table to find the fb value for your floor joists. as an example, consider a room with a floor area of 10 feet by 11 feet.calculated the gsm of your material,to calculate the gsm of your material, simply fill out the fields above and select the correct units. it’s free and easy to use! this calculation is commonly used for nonwoven materials, paper, plastic and other thin materials. the most common way to measure gsm is using a scale and a ruler, but there are sometimes other methods needed for industrial processes.
formulas used on the car math here are the formulas for most of the car math calculators . * many of the formulas use the value of pi which is 3.1415927 * some formulas contain notation such as ^2 which means 'squared' or ^3 which means 'cubed' formulas for calculating carburetors cfm engine size (cid) x maximum rpm / 3456 = cmf.barlow's formula calculator,barlow's formula calculator. barlow’s formula is a calculation used to show the relationship between internal pressure, allowable stress (also known as hoop stress), nominal thickness, and diameter. it is helpful in determining the maximum pressure capacity a pipe can safely withstand. the formula is expressed as p=2st/d, where: p. pressure.roll forming calculations,51. you need to calculate the circumference of the mean diameter of the ring you are rolling. example: if you are rolling a ring with a 12 inch od out of .25 inch thick material, the mean diameter of the ring will be 11.75 inches. the length of the material will then be 11.75 x
and % pb in perfect concentrate = 11.545 x 5 = 57.7%. and % cu in perfect concentrate = 11.545 x 1 = 11.54%. or, directly by (32), % pb = 86.58 x 5/5 + 2.5 = 57.7%. similar formulas for other mineral associations, for example, galena and chalcocite.handy charts and formulas for the pressure washer professional,gpm = nozzle # / (psi / 4000) psi = in. hg x .4912. in hg = in h2o x .07355. cubic inches = gallons x 231. top. these charts are accurate to the best of our knowledge. if you note any discrepancies, please e-mail administrator . the above formulas are for information only, hydro tek recommends consulting a pressure washer professional for all.rolling mills: 6 different types of rolling mills [images,in the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. the types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. because of workability and limitations in equipment, rolling is done in the
chain construction the roller chains generator is intended to design chain drives with roller and bush chains. the chains can have single strand or multiple strands. the double-pitch chains are also supported. typical construction of roller and bush chains is shown in the following picture. the main difference is that bush chain does not have a roller.calculations of internal gears and the fundamentals of,it will become a standard gear calculation if x1 = x2 = 0. if the center distance, ax, is given, x1 and x2 would be obtained from the inverse calculation from item 4 to item 8 of table 5-1. these inverse formulas are in table 5-2. pinion cutters are often used in cutting internal gears and external gears..textile calculations and equations,conversion formula from percentage to g/l is as g/l = required amount (%)× 10 40. recipe calculation 41. dyes and chemicals measuring formula for laboratory: the amount of dye solution (ml) is calculated as follow – the amount of chemical soln (ml) is measured as follow – 42.
for mills that only make a few formulas, the efficiency factor might be increased to 90% or more. assuming the capacity rates required in table 1 are for a commercial feed mill, making numerous different formulas, the design capacity rate would be 60 tph/.80 = 75 tph. we will use this design capacity in several places in future articles..milling horsepower calculator,milling horsepower calculator. calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). also required is the unit power, which is a material property describing the amount of power required to cut that material..positive displacement blower calculations,now days we have computer programs that can calculate positive displacement blower performance. they are a time saver and can quickly give you many options. before selection programs, performance was calculated by hand to determine required performance. these equations will give the user a better understanding of how performance for a positive displacement blower is calculated.
note 1: 'b' is the bevel or miter angle setting for saws that calibrate a square cut at zero degree. for saws that calibrate a square cut at 90 degrees, use the complement of b for the saw's setting.note 2: dimension 'm' is useful in projects that involve rounding off the corners of a polygon to form a round or cylindrical shape.dimension mwill tell you the thickness of the material where the.coil-fed processing: 4 quick formulas for production planning,all we need is measuring the coil outer diameter, inner diameter and thickness. with these information, first we calculate the volume of the metal coil: (volume) = 3,14/4*(od^2-id^2)*w.pipe thickness calculation (internal pressure design,step 1. put the above values in the equation shown in fig. 1. t=(1200*114.3)/{2(19000*1*1+1200*0.4)}=3.52 mm; hence calculated thickness (t)= 3.52 mm. step 2. add the corrosion to the calculated thickness. t c = t + c = 3.52 + 3 t c = 6.52 mm. step 3. add the mill tolerance to the thickness after adding corrosion value.
the formula to calculate the area of a rectangle: area = length x width example 1: calculate the area for the following cases. 18” l x 10” w x 8” h → a = l x w → 18 x 10 = 180 square inches or 180 in2 12” l x 8.5” w x 14” h → a = l x w → 12 x 8.5 = 102 square inches or 102 in2.manufacturing calculators and widgets,milling speed and feed determine the spindle speed (rpm) and feed rate (ipm) for a milling operation, as well as the cut time for a given cut length. milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill.
