HOW MUCH WATER IN m OF 28mm COPPER PIPE?

To calculate the volume of water in a 28 mm copper pipe, you first need to determine the internal diameter. Assuming a standard wall thickness for copper pipe, the internal diameter is approximately 26 mm (0.026 m). The volume (V) of water in the pipe can be calculated using the formula ( V = \pi r^2 h ), where ( r ) is the radius (0.013 m) and ( h ) is the length of the pipe in meters. Thus, for a 1-meter length of pipe, the volume would be approximately 0.00053 m³, or 530 mL.
