* The animation shows the flow velocity simulation of the air flow line in the center of the air duct. The flow line changes from blue to red, indicating that the pressure loss in the pipe is increasing. (Red is the high loss area). Use Haaland Equations and Colebrook Pipe Resistance Fluid Dynamics for accurate solution.
