I have a plate 100mm Outer x 50mm Inner and length is 200mm. how can i find weight of this round bar in kg or gram
It is a gun metal pipe. Weight pi * [OD^2 - ID^2] / 4 * Length * Density Weight 3.14 [ (100/1000)^2 - (50/1000)^2] / 4 *200/1000 *Density Weight 3.14[0.1^2 - 0.05^2] / 4 * 0.2 * density Weight 3.14[0.0075]/4 *0.2 *density Weight 0.0011775 * Density [ In kilo-gram ] Weight 0.0011775 * 8960 Weight 10.55 kg Density taken is approximately 8960 kg/m^3 as it contains 88% of copper.
Take a container ( should be flask type ) and fill with water and dip ur bar and try to find the volume of that. If u get the volume then Density Mass / Volume Using this u can get the mass Weight Mass * g
