(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?
The specific gravity of the mixture is 0.911.

An object that can float in both water and in oil (whose density is less than that ofwater) experiences a buoyant force that is
(a) Greater when it is floating in oil than when floating in water.
(b) Greater when it is floating in water than when floating in oil.
(c) The same when it is floating in water or in oil.
If cholesterol buildup reduces the diameter of an artery by 25%, by what % will the blood flow rate be reduced, assuming the same pressure difference?
A fire hose exerts a force on the person holding it. This is because the water accelerates as it goes from the hose through the nozzle. How much force is required to hold a \({\bf{7}}{\bf{.0}}\;{\bf{cm}}\)-diameter hose delivering \({\bf{420}}\;{\bf{L/min}}\)through a \({\bf{0}}{\bf{.75}}\;{\bf{cm}}\)-diameter nozzle?
(I) If the force \(F\) needed to move the wire in Fig. 10–34 is \(3.4 \times {10^{ - 3}}\;{\rm{N}}\), calculate the surface tension \(\gamma \) of the enclosed fluid. Assume \(l = 0.070\;m\).
A viscometer consists of two concentric cylinders, \({\bf{10}}{\bf{.20}}\;{\bf{cm}}\) and \({\bf{10}}{\bf{.60}}\;{\bf{cm}}\)in diameter. A liquid fills the space between them to a depth of \({\bf{12}}{\bf{.0}}\;{\bf{cm}}\). The outer cylinder is fixed, and a torque of \({\bf{0}}{\bf{.024}}\;{\bf{m}} \cdot {\bf{N}}\) keeps the inner cylinder turning at a steady rotational speed of \({\bf{57}}\;{\bf{rev/min}}\). What is the viscosity of the liquid?
