Abstract
The pressure loss due to friction was measured for conduits ranging from 3/4 in. to 1 1/4 in. nominal diameters containing up to three insulated copper wires. The air flow rates used gave Reynolds numbes ranging from 5,000 to 50,000. It was found that all the results could be correlated in terms of an equivalent diameter, i.e., the diameter of an empty conduit which would have the same pressure-loss - mass-flow characteristics as the conduit containing wire. The ratio of equivalent diameter to conduit diameter was found to depend primarily on the ratio of wire diameter to conduit diameter and the number of wires in the conduit, and only slightly on the Reynolds number.
