An antique airplane carries \(50 \mathrm{~m}\) of external guy wires stretched normal to the direction of motion. The wire diameter is \(5 \mathrm{~mm}\). Estimate the maximum power saving that results from an optimum streamlining of the wires at a plane speed of \(175 \mathrm{~km} / \mathrm{hr}\) in standard air at sea level.
