A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead, the pipe's diameter is 56.5 cm and the flow speed of the petroleum is 10.1 m/s. At the refinery, the petroleum flows at 6.43 m/s. What is the volume flow rate Q of the petroleum along the pipe, and what is the pipe's diameter d at the refinery? Q = 2.53 m' /s d = 0.707 cm Incorrect
