Average surface roughness for drawn tubing e is 0.000005 ft. If the conductor has the same 1-in. tubing with 0.049-in. wall thickness, the ratio of roughness to ID will be 0.000067. The Moody diagram indies that the Reynolds nuer for this conductor must be at least 25,000 before the inside surface exposes its resistance to fluid flow.
