(5 pts.) Water is contained between two sets of large plates as shown below. The upper plates are pulled to the right, while the bottom surface is stationary. The flow is laminar. What is the ratio of F2/F1 if both the height of the space on the left is four times that of the height on the right (h1=4h2) and the velocity of the upper plate on the left is three times times that of the upper plate on the right (V1=3V2)
