Non-Circular Pipe Flow - Hydraulic Diameter Example Problems
1 FE Exam Style Hydraulic Diameter Example Problem + 1 regular non-circular conduit homework problem including Moody Diagram, Friction Coefficient, and the Darcy Weisbach Equation.
Master Fluid Mechanics with my full course playlist: • Fluid Mechanics
Main emphasis is how to find hydraulic diameter, and you'll need the cross sectional area and the wetted perimeter. This video will also show you how to use the FE Reference Manual to find hydraulic diameter equation, power loss equation, Moody diagram, and smoothness coefficient.
