An unsteady flow of a viscous incompressible fluid between two disks with reference to non-coaxial parallel axes of rotation has been studied. It is rigorously stated that there arises an axisymmetric solution of this problem in the case of a rigid body rotation. An exact solution of the governning equations has been obtained by applying the Laplace transform technique. The torque, required to overcome the transverse shearing stress on a disk, has also been calculated. It is found that the torque obtained from the general solution on the disks decreases with an increase in time. On the other hand, for small time the torque on the disks increases with an increase in time.
