To calculate cubic feet, multiply the thickness in feet by the square footage. Convert a measurement in inches to a measurement in feet. Calculate the square footage by measuring the length and width of the area to be covered.

Unit weight of Steel Bar (in Kgs) = (D^2)/162.28 ~ (D^2)/162 How to calculate concrete slab thickness Decide on the desired thickness of the concrete. To simplify, we can reciprocate the decimal figure here i.e., (1/0.006162) and get a figure of 162.28 Calculate or enter the area, choose the number of layers of reinforcing mesh and indicate de coverage and floor zone. Unit Weight of Steel Bar (in Kgs) = (3.14 X D^2)/4 X 1000 X 7850 / (1000 X 1000 X 1000) Calculate the number of reinforcing mesh in 3 steps. So considering these data in the Weight formula we get Since We are trying to calculate the unit weight of Steel Bar, the length of Steel Bar in the calculation would be 1 mtr or 1000 mm.ĭensity of Steel Bar = 7850 Kgs/Cu.m = 7850/(1000X1000X1000) Cubic mm Pad Width, Pad Length A, Pad Length B and Radius determine the size of the pad. Volume of Steel Bar (Cu.m) = Area of Steel Bar (sq.mtr) X Length of Steel Bar (mtr) The outside edge of the pad is rectangular. The insret can be square with 2'-3' radius round corner.

Weight of Bar (in Kgs) = Volume of Steel Bar (in Cu.m) X Density of Steel Bar (in Kgs/Cu.m) If using insert plate, which is not uncommon, making sure the width of the insert plate, measured from outside of the nozzle, is not less than: square root (RxT) plus width of the taper section (which in your case will be 1.125' for a 3:1 taper). Providing additional material in the region of the opening by thickening the shell or adding a pad material is known as reinforcement. Many reading this blog might know that the unit weight of a steel bar is calculated by a forumla D^2/162 (Note: D unit is in MM) but do you know how its derived?ĭensity of Steel (in Kgs/Cu.m) = Weight of Steel (in Kgs)/Volume of Steel (in Cu.m)
