An attempt to evaluate the vortex strength of a vortex (or a few vortices) generated behind a circular cylinder located in a uniform flow is given. In order to obtain the vortex strength, the least square method combined with the velocity potential theory is applied to the data of velocity vector distribution. Vortex strength obtained in this way is examined by changing the area of data sampling. The ability that the potential theory using the above otained vortex strength would represent the actual velocity field is also examined.
