The Moody-Diagram Hulk has spoken truth! Engineering students everywhere just collectively shuddered. That friction factor chart is the ultimate nemesis - logarithmic scales in multiple directions, curves that barely distinguish themselves, and tiny numbers that require superhuman vision. The irony is perfect - you need Hulk-level strength just to interpret fluid dynamics data without having a breakdown. Even the mighty Hulk himself is overwhelmed by these "confusing lines" that determine whether your pipe flow is laminar, turbulent, or just plain impossible to calculate without crying.
