Water, p=998 kg/m, p=0.001 Pa-s, flows through a rough pipe of diameter 3 cm at 30 m/h. If the surface roughness is 0.1 mm, compute: a) The Darcy's friction factor A and the skin friction coefficient C. Verify with Moody's chart. Hint: You may use Haaland's formula for A first and then use Colebrook's formula for one iteration correction. b) The wall shear stress T. c) The pressure drop per meter.
