This work was undertaken to study the effect of wake upon the resistance of plane net set parallel to a stream. In this paper, the resistance of a parallel set of wires is reported. The methods and the apparatus are shown in Figs. 1 and 2, and results obtained are as follows: 1) The velocity of the stream around the surface of the set of parallel wires is uniform, when the direction of stream is parallel to the set of wires and each of which is set vertically against the stream. 2) The velocity of the stream running around the wires is decreased due to the wakes, when the angle between the direction of stream and of the surface of the set of parallel wires is small. 3) The resistance of the wire in wake can be calculated be the ordinary formula of velocity decrement in a wake.
