Question
Ethanol at 20°C flows at 125 U.S. gal/min through a horizontal cast-iron pipe with L = 12 m and d = 8 cm. Neglect entrance effects. For ethanol, take p=789 kg/m³ and μ = 0.0012 kg/m-s. For the given flow take fMoody≈ 0.0282 and smooth ~ 0.0187. Estimate the wall shear stress Tw for the given flow. The wall shear stress is Pa.
