kg = 6.16546 x width mm x OD2 x bore2 ---- 1000000
Formula to calculate length of spiral reinforcement in columns
Weight of pipe per Meter in Kg for MS Pipes = 3.14 * (Outer diameter of pipe in Mtr. - wall thickness in Mtr. ) * Wall Thickness in Mtr. * 7850
ON the cad offset the bend radius from the internal radius of the sheet metal part by 40% of the total sheet thickness,and measure the chord length of the radius. that will be the developed length.
I dnt kno..:I
The hollow block sizes in the Philippines are the following:40cm (length) X 20 cm (width) X 4 in (thickness)40cm (length) X 20 cm (width) X 5 in (thickness)40cm (length) X 20 cm (width) X 6 in (thickness)
AREA*THICKNESS(length)*7.85 pi*r2*t*7.85 - in mm
density=mass/volume 7.850=2500kg/(0.47*L*0.914) Ravindra
It looks like you meant width or thickness. This is the formula to calculate volume or capacity of a rectangular prism (a box).

There is no formula to calculate the length of a wire. The length of a wire is determined by the distance from the power source to where the load is situated.
If the bar is a three dimensional object it will have some thickness. Then, assuming it is oblong in shape and knowing its length, width and thickness: Surface_area = 2 x (length x width + width x thickness + thickness x length)
Depending on the shape of the solid thickness of the material varies. Thickness=Volume/(length x width) for a rectangular prism. Thickness can also be measured with the help of a vernier calipers.
Weight of pipe per Meter in Kg for MS Pipes = 3.14 * (Outer diameter of pipe in Mtr. - wall thickness in Mtr. ) * Wall Thickness in Mtr. * 7850
Density = Mass / Volume the Volume is what you just said ... length x width x thickness
A point has no length, width, or thickness. A line has infinite length but no width or thickness. A plane has infinite length and width but no thickness.
Job workers using this formula as given :- total hrs. in Single pass (Single cut)=Total Path length x job thickness / 1500 total hrs. in Double pass (Double cut)=Total Path length x job thickness / 1200 total hrs. in Triple pass (Triple cut)=Total Path length x job thickness / 900 total hrs. in Four pass (Four cut)=Total Path length x job thickness / 600 and the Rates are Rs.200.00/hr to Rs.250.00/hr.
i dont know.... plz tel how to calculate
