Fan Power Required for Flow Through a Rough Pipe | Moody Chart Example

Determine the required fan power to force air through a long galvanized iron duct using the energy equation, Reynolds number, relative roughness, and Moody chart. In this fluid mechanics example, air flows through a iron duct. We calculate the average flow velocity, determine whether the flow is laminar or turbulent, obtain the Darcy friction factor from the Moody chart, calculate the major head loss, and determine the required fan power in horsepower. This example demonstrates how pipe roughness and friction losses affect the power required from a fan in an internal-flow system. #FluidMechanics #MoodyChart #PipeFlow #FanPower #Engineering #MechanicalEngineering #ReynoldsNumber #HeadLoss
