two segments: 100 ft of 8" DIP and 100 ft of 10"DIP. There is a sudden expansion between the two segments. The 10" segmentincludes a swing-type check valve, fully open. Find the discharge through the pipe. Use the Darcy equation for pipe friction loss,assuming fully turbulent flow. Verify if flow is or is not fully turbulent, but no need to iterate if you discover flow is not fully turbulent
