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 \({{\bf{v}}_{\bf{1}}}{\bf{ = }}\sqrt {\frac{{{\bf{2gh}}}}{{\left( {{\bf{1 - A}}_{\bf{1}}^{\bf{2}}{\bf{/A}}_{\bf{2}}^{\bf{2}}} \right)}}} \),
where \({\bf{h = }}{{\bf{y}}_{\bf{2}}} - {{\bf{y}}_{\bf{1}}}\), and \({{\bf{A}}_{\bf{1}}}\) and \({{\bf{A}}_{\bf{2}}}\) are the areas of the opening and of the top surface, respectively. Assume \({{\bf{A}}_{\bf{1}}}{\bf{ < < }}{{\bf{A}}_{\bf{2}}}\) so that the flow remains nearly steady and laminar.

If one material has a higher density than another, must the molecules of the first be heavier than those of the second? Explain.
A small amount of water is boiled in a 1-gallon metal can. The can is removed from the heat and the lid is put on. As the can cool, it collapses and looks crushed. Explain.
(I) Engine oil (assume SAE 10, Table 10鈥�3) passes through a fine \({\bf{1}}{\bf{.80}}\;{\bf{mm}}\)-diameter tube that is \({\bf{10}}{\bf{.2}}\;{\bf{cm}}\)long. What pressure difference is needed to maintain a flow rate of \({\bf{6}}{\bf{.2}}\;{\bf{mL/min}}\)?
(II) If 4.0 L of antifreeze solution (specific gravity = 0.80) is added to 5.0 L of water to make a 9.0 L mixture, what is the specific gravity of the mixture?
