06: The Flat middle plate (30 em x 30 cm) shown in figure is pulled at 3m/s due to the force F. The velocity of the lower plate Vip is 0.3 m/s. The dynamic viscosity u of the oil is 0.027 Pa.s and of the water (u 1642 x 10% P2,8). Assume a linear distribution of velocity. Upper Plate Water mm + 3 m/s 2.6 mm Oil Middle Plate Lower Plate 0.3 m/s i Draw the velocity profile and locate where the oil velocity is zero. Determine the force F. At what speed and in what direction must the upper plate be moved to hold the center plate stationary? 06: The Flat middle plate (30 em x 30 cm) shown in figure is pulled at 3m/s due to the force F.
