Problem $6$ A flat plate is pulled with a speed of $6\mathrm{.}2$ m$/$s relative to another plate which is parallel to the first plate. The space between the two plates is filled with a fluid and the thickness of the fluid film is $16\mathrm{.}6$ mm$.$ Area of the plate is $80$cm$\backslash$times $80$cm$.$ The moving plate requires a force of $100$N to maintain the speed. a$)$ Determine the dynamic viscosity of the fluid. b$)$ Determine the kinematic viscosity of the fluid if the specific gravity is $0\mathrm{.}82$
