The exact number of cans per pound can't be quantified due to different measurements. Depending on the brand, estimates show there are usually 32 to 35 cans per pound. For smaller, more common 12 ...
According to the International Resource Panel's Metal Stocks in Society report, the per capita stock of steel in use in Australia, Canada, the European Union EU15, Norway, Switzerland, Japan, New Zealand, and the US combined is 7,085 kilograms (15,620 lb) (about 860 million people in 2005).
A standard flexible intermediate bulk container can hold 500 to 1,000 kg (1,100 to 2,200 lb) and manufacturers offer bags with a volume of 285–2,830 litres (10–100 cu ft). [2] Flexible intermediate bulk containers are made of woven polyethylene or polypropylene or other heavy polymers.
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.
The value for zinc in seawater is 780 Ah/kg but aluminium is 2000 Ah/kg, [14] which reflects the lower atomic mass of aluminium and means that, in theory, aluminium can produce much more current per weight than zinc before being depleted and this is one of the factors to consider when choosing a particular material.
A standard wire gauge. The British Standard Wire Gauge, often referred to as the Standard Wire Gauge or simply SWG, is a unit used to denote wire gauge (size) as defined by BS 3737:1964, a standard that has since been withdrawn. It is also known as the Imperial Wire Gauge or British Standard Gauge. Although its use has significantly declined ...
The resistance of copper wire is approximately 1 Ω / 1000 ft for 10 AWG, 10 Ω / 1000 ft for 20 AWG, 100 Ω / 1000 ft for 30 AWG, and so on. [5]: 27 For an arbitrary gauge n, it's approximately 10 n/10 Ω per 10 000 ft.
In practice, maximum current density can vary from 2.5 A/mm 2 for a wire isolated from free air to 6 A/mm 2 for a wire in free air. [ citation needed ] If the wire is carrying high frequency currents (above 10 kHz), the skin effect may affect the distribution of the current across the section by concentrating the current on the surface of the ...
