The hydrodynamic equations of stellar dynamics are used to study the flow around a point mass (M) - a globular cluster - moving through a homogeneous star field at constant velocity (V). A formula is derived for the increment in stellar density projected onto a map surface as compared to the nondisturbed spatial density. A characteristic parameter for this increment is the quantity 2GM divided by V squared. Therefore, knowing the velocity of the globular cluster in relation to the local centroid, it is possible to determine the mass of the cluster, including the mass of a black hole if there is one in its center, on the basis of star counts in the vicinity of the cluster.
