Note that the "nominal" size (e.g., 2-inch pipe) is rarely the exact internal diameter. Always use the actual ID based on the pipe schedule (like Schedule 40 or 80 PVC).

High-pressure systems can be dangerous. Calculating flow ensures that the velocity doesn't exceed the structural limits of your plumbing or industrial fittings. 3. Troubleshooting
