four numbers.
It depends on what material and how many there are in the bundle.
A standard bundle of 10 mm steel bars typically contains around 100 to 150 pieces, depending on the manufacturer and regional standards. The total weight of the bundle can vary, but it generally ranges from 1,000 to 1,500 kilograms (approximately 2,200 to 3,300 pounds). It's always best to check with the supplier for specific bundle sizes and weights.
The length of an 8 mm bar in a bundle (often referred to as a "bandal") can vary depending on the manufacturer and regional standards. Typically, the standard length for reinforcement bars, including 8 mm bars, is around 12 meters (approximately 39.37 feet) per bundle. However, it's essential to check with local suppliers for specific lengths and bundle sizes.
8.8 is a quality measurement, 20 mm is a size measurement. They're not dependent on each other. You can have a 20 mm bar in any quality, as you can have an 8.8 quality bar in any size.
20 mm
It would take 20 pieces of 3 mm thick paper to make a stack that is 6 cm thick. This is because 1 cm is equal to 10 mm, so each piece of paper adds 3 mm to the height of the stack.
20 mm should still be 20 mm!
The weight of a bundle of 8 mm Rathi steel TMT bars can vary based on the length of the bars and the specific number of bars in the bundle. Generally, a standard bundle of 8 mm TMT bars weighs around 500-600 kg, but this can differ based on manufacturer specifications. To get the exact weight, it's best to consult the supplier or check the packaging details.
All U.S. bills are approximately 0.11 mm thick. I.e. a stack of 9 of them is about 1 mm high. In inches, a single bill is about 0.0043 inches thick. A standard bundle of 50 bills ($50 to $5000) is about 5.5. mm high (0.215 in at 233 to the inch).
None but 20 mm = 2 cm
10m (10,000 mm) of water column is about 0.98 bar (P=density*specific gravity*height=1000*9.8*10) 5000 mm WC is 0.49 bar then.
20 mm - 0.2mm = 19.8
