(III) In Fig. 10–54, take into account the speed of the top surface of the tank and show that the speed of fluid leaving an opening near the bottom is 2gh (1 – A{/A}) where h = y2 – yı, and A1 and A2 are the areas of the opening and of the top sur- face, respectively. Assume A1 « A2 so that the flow remains nearly steady and laminar. y2-y1 FIGURE 10–54 Problem 55.
