A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead the pipe's diameter is 58.3 cm (0.583 m) and the flow speed of the petroleum is 13.1 m/s. At the refinery the petroleum flows at 5.81 m/s. What is the volume flow rate of the petroleum along the pipe and what is the pipe's diameter at the refinery? Volume flow rate: Number m³/s
