In ref. [1] the authors claimed that there are two values of the film thickness. Also, the authors found that the local skin-friction coefficient independent on the viscosity parameter. In the present study it is derived that the film thickness is equal to one. Also, the local skin-friction coefficient is found to depend on the viscosity parameter. It is found that the unsteadiness parameter has one value, which satisfy the constraint condition, for each value of the various parameters when the others are fixed.
