A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead the pipe\'s diameter is 58.5 cm and the flow speed of the petroleum is 13.9 m/s. At the refinery the petroleum flows at 6.53 m/s. What is the volume flow (m^3/s) rate of the petroleum along the pipe and what is the pipe\'s diameter (cm) at the refinery?
