The problem is considered for symmetric collision of weakly disturbed contrary plane jets of perfect incompressible fluid flowing out from channels when laws of changing of pressure or velocity in infinity remote points are given. The boundary problem is posed for the potential of disturbed flow. The form of free boundaries is found for moments of time for the cases of parallel walls and variation harmonic laws for the flow at infinity. The graphs are given for the distribution of the pressure coefficient on line of symmetry of this flow.
