The viscous incompressible fluid is considered between two disks which are spaced a distance H√ (1-αt) and rotating with angular velocities. The governing Navier-Stokes equations reduced to a pair of nonlinear differential equations. We obtain the solution to these equations by computer extended perturbation series solution with special reference to normal forces and torques. The coefficient of the parameter (-g'(0)) decreasing in magnitude and alternating sign. By Domb-sykes plot, the singularity is identified. The series is recasted using Euler transformation. But the coefficients of f'''(0) decreasing in magnitude having fixed sign pattern is recasted using reversion.
