As an illustration of Couette flow, the space between two very long parallel plates separated by distance 0.2 m is filled with SAE 30 oil at room temperature (20◦C), as illustrated in Figure ECP 1.94. The lower plate is held stationary while a continuous tangential (shear) force, FV is applied to the upper plate, thus moving the plate with a constant velocity of 0.15 m/sec. The dimensions of the upper plate are 3 m by 1.5 m. (a) Determine if the flow is laminar or turbulent. (b) Graphically illustrate the velocity profile at the cross section of flow. (c) Graphically illustrate the shear stress at the cross section of flow. (d) Determine the magnitude of the shear force required to keep the plate moving at the given constant velocity
