Measure the mass (in kilograms) and length (in metres) of the strip. Divide the first by the other.
Copper has a CTE of 16.6 parts per million/degree C (16.6E-6/C)
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
In order to calculate the internal capacity of a pipe use the formula pi x internal radius x internal radius x length of pipe where pi = 3. 142. This is the volume of a cylinder; pipe capacity is usually amount of flow per unit of time under given conditions of internal roughness, and viscosity of the flowing fluid with a given pressure loss per length unit
The way I have done this with things such as heaters, window defrosters, etc. is to model the heating element as a resistor (or a set of resistors in different parallel and series combinations, based on the layout). The wire used in the electric blanket (the heating elements) should have a specific resistance per length; calculate the length of the different sections, and create a lumped resistive element of this total length.
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
You convert everything to a common unit, for example meters, multiply length x width x height to get the volume, then multiply this volume by the density of copper, which you can easily look up. - Actually this will give you the mass, not the weight. If you really want the weight, you can multiply the mass by Earth's gravity - about 9.8. Alternately, you can weigh a sample.
Copper is priced in terms of its mass, not its length.
(rho) or resistivity of a "wire" is calculated using this formule:rho = Resistance x Area / length of materialthe resistivity of copper is 1.7 x 10 -8 ohm/mResistivity is measured in ohm metres, NOT ohms per metre!
200*75*7
It is not possible to calculate weight just from length, width and/or height. (These can give you volume and area, but not weight). For weight, you need to know "how heavy it is per this amount of stuff" is - e.g "3 grams per square cm" or "6 tonnes per inch".
Calculate the volume = length * breadth * thickness, where these are measured in centimetres. Multiply by the density = 8.96 grams per cubic centimetre to obtain the mass in grams. Divide by 1000 to get the mass in kilograms. Finally, multiply by 9.8, the acceleration due to gravity. The answer is the weight, in Newtons.
500mcm 37 strand copper wire = 1.544lbs/ft.
$ 4.34 per pound of copper. according to the world copper price market.
You must know the length of a R.R. car. Time the trains cars as they pass from a given point to the next. Now you divide time into that length to get feet per second. Do the math to get miles per hour.
You look up the specific heat of copper (per mass unit). Then you multiply specific heat x mass x temperature difference.
Copper prices moved up by 0.83 per cent to Rs 377.30 per kg
As of Aug 18, 2008 Large Copper Motors are around $40 cents per lb No 1 bare brite copper wire is around $3 per pound No 1 copper wire scrap is around $2.87 per pound Copper turning are around $2.28 per lb
