We have been given the task of rigging a copper pipe with a wall thickness of 1/16 of an inch. Before selecting our rigging equipment, we need to know the weight of the pipe. We have available the weight of material chart that provides weight by area and thickness. To calculate the weight of this pipe, we need to find its area and then multiply it by the weight of copper for a 1/16″ thickness. We can do this by multiplying the value of pie, times the outer diameter, times the height. Using our measuring tape, we find that the outer diameter measures 4 feet, and the height measures 10 feet. We now can multiply the value of pie, which is 3.14, times 4 feet, times 10 feet, for a value of 125.6
we now multiply this value times the weight of 1/16 of an inch copper, from the chart. that is, we multiply 125.6, times 2.89, giving us the weight of our copper pipe, which comes to 362.98 pounds.
