Ethanol at 20°C flows at 0.008 m³/s through a horizontal cast iron (ε = 0.26 mm) pipe with L = 12 m and d = 5 cm. Neglecting entrance effects, estimate (a) the pressure gradient dp/dx, (b) the wall shear stress Tw, and (c) the percentage reduction in friction factor if the pipe walls are polished to a smooth surface. Ethanol properties at 20 °C: p=789 kg/m³, μ = 0.0012 kg/m.s
