Chapter 10: Q80GP (page 260)
How high should the pressure head be if water is to come from a faucet at a speed of \({\bf{9}}{\bf{.2\;m/}}{{\bf{s}}^{\bf{2}}}\) Ignore viscosity.
Short Answer
The height of pressure head is\(4.31\;\;{\rm{m}}\).

Get started for freeA 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.
During each heartbeat, approximately \({\bf{70}}\;{\bf{c}}{{\bf{m}}^{\bf{3}}}\) of blood is pushed from the heart at an average pressure of 105 mm-Hg. Calculate the power output of the heart, in watts, assuming 70 beats per minute.
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?
When you ascend or descend a great deal when driving in a car, your ears “pop,” which means that the pressure behind the eardrum is being equalized to that outside? If this did not happen, what would be the approximate force on an eardrum of area \(0.20\;c{m^2}\)if a change in altitude of 1250 m takes place?
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.
