How do you calculate the weight of steel?
How do you calculate the weight of steel?
STEEL QUANTITY:
- Weight of bar in kg/meter should be calculated as (d2 ÷ 162) where’d’ is the diameter of bar in mm.
- ‘L’ for column main steel in footing should be considered as minimum 30cm/as specified.
- For bent up bar add 0.42d in straight length of bar where’d’ is the clear depth of beam/slab.
How do you calculate rust?
Corrosion rate is best expressed in terms of thickness or weight loss where the surface of the metal corrodes uniformly across the area that has been exposed. It is found by: R = d/t expressed in µm/y but can also be expressed in terms of: Weight loss g/m2.
What is the weight of steel?
One cubic inch of steel weighs 0.283 pounds. So, a 1″ square piece of steel 1 foot long weighs (1 X 1 X 12 X . 283) or about 3.4 pounds.
What is steel formula?
Steel is an alloy and has no structural formula. It is composed of Iron (Fe) with small amounts of carbon (C). Unalloyed steel contains from 0.002% to 2.1% carbon.
How do you calculate steel?
Multiply the total length of bar with the following unit weight. For, 10mm ø bar = 0.617 kg/m. 12mm ø bar = 0.888 kg/m….
- 10mm ø bar = 0.188 kg/ft.
- 12mm ø bar = 0.270 kg/ft.
- 16mm ø bar = 0.480 kg/ft.
- 20mm ø bar = 0.750 kg/ft.
- 25mm ø bar = 1.172 kg/ft.
What is the weight of a 40 kg mass?
If an object has a mass of 40 kg on Earth it will have the same mass on the Moon. But, on a scale on Earth the 40 kg mass will weigh about 88 pounds. On the Moon it would weight about 14.7 lbs because the gravity there is 1/6 that on the surface of the Earth. The weight of an object is 1/6th than that of on Earth.
How do you calculate weight in kilograms?
In physics the standard unit of weight is Newton, and the standard unit of mass is the kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.
What is the rate of rusting?
Steel corrodes quickly in acidic environments and slowly or not at all as alkalinity is increased. The corrosion rate of steel in soil can range from less than 0.2 microns per year in favorable conditions to 20 microns per year or more in very aggressive soils.
What is K in corrosion rate formula?
where K is a constant, W (mg) is the weight loss of the metal after exposure time t, A is the surface area of the metal exposed, and ρ is the density of the metal (in g/cm³). The constant K = 534 for CPR in mpy, and 87.6 for mm/yr (unit of A is in cm) A simple test for measuring corrosion is the weight loss method.
How do you calculate tons of steel weight?
If we put 1 meter length for each diameter of steel bar in the formula then we will get the unit weight. If we multiply the length of bars with this unit weight we will get the total weight of steel bars. For example, the total weight of 1000 meter long 20mm ø steel bar is, 1000 x 2.469 = 2469 kg.
What is 162 in steel weight calculation?
Calculation Of The Formula D²L/162: The weight of steel bars= Cross sectional area of steel bar x Length of steel bar x Density of steel bar.
What is the chemical equation for rusting of iron?
Fe (OH) 3 ⇌ FeO (OH) + H 2 O. FeO (OH) ⇌ Fe 2 O 3 + H 2 O. One similarity between all the chemical reactions listed above is that all of them are dependent on the presence of water and oxygen. Therefore, the rusting of iron can be controlled by limiting the amount of oxygen and water surrounding the metal.
How do you calculate the weight of a steel tube?
Steel Tube Weight Calculation Formula (outside diameter – wall thickness) * wall thickness(mm)*0.02466*Length(m) If the outside diameter is 20mm, wall thickness is 5mm and the length is 5m You can get that: (20-5)*5*0.02466*5=9.2475kg
What is the weight of 1m of steel?
Steel Weight Calculation 1 1M=3.281″ 2 1″=25.4MM 3 1 Pound=0.4536 Kilogram 4 1 Kilogram Force=9.81 N 5 1 MPa=145.161 Pound/Inch 6 The density of steel: 7.8g/cm³ 7 The density of stainless steel: 7.78g/cm³ 8 The density of aluminum: 27g/cm³
How do you calculate the weight of a round steel bar?
Steel Round Bar Weight Calculation Formula Diameter (mm)*Diameter (mm)*0.00617*Length (m) If the diameter is 20mm and the length is 10m You can get that: 20*20*0.00617*10=24.68kg Square Steel Weight Calculation Formula
