A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead, the pipe's diameter is 54.7 cm and the flow speed of the petroleum is 13.9 m/s. At the refinery, the petroleum flows at 6.45 m/s. What is the volume flow rate of the petroleum along the pipe, and what is the pipe's diameter at the refinery
