A theoretical investigation is made of a circular jet issuing from an orifice into an air stream flowing parallel to the jet axis and in the same direction as the jet. The analysis is divided into two portions: 1) the region immediately downstream of the orifice in which exists the potential cone of uniform velocity, 2) the region downstream of the end of the potential cone in which the jet is fully developed. The solution for these two portions are fitted together at the section at which the potential cone disappears giving a complete solution for the whole jet. Numerical computations are made for several ratios of free stream velocity to jet velocity to determine the spread of the jet, velocity on the axis of the jet, and spread of the surface on which the velocity is one half the sum of the jet velocity and free stream velocity. Squire and Trouncer's results are plotted as a comparison with those obtained in this analysis,
