Question

4. A parallel plate viscometer has a plate that is 200mm long by 100mm wide. It sits atop a film of fluid that is 1.5mm thick. The fluid has a mass density of ρ=800kg/m3. Assume that it behaves as a Newtonian fluid. It is pulled horizontally by a constant force of F=5N and at a constant speed of V=12m/s. Find the kinematic and the dynamic viscosity of the fluid.
