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 freeThree containers are filled with water to the same height and have the same surface area at the base, but the total weight of water is different for each (Fig. 10–46). In which container does the water exert the greatest force on the bottom of the container?
(a) Container A.
(b) Container B.
(c) Container C.
(d) All three are equal
A submerged can of Coke sink, but a can of Diet Coke will float. (Try it!) Explain.
(II)A fish tank has dimensions 36 cm wide by 1.0 m long by 0.60 m high. If the filter should process all the water in the tank once every 3.0 h, what should the flow speed be in the 3.0 cm diameter input tube for the filter?
(II)A 180 km/h wind blowing over the flat roof of a house causes the roof to lift off the house. If the house is\(6.2\;{\rm{m}} \times {\rm{12}}{\rm{.4}}\;{\rm{m}}\)in size, estimate the weight of the roof. Assume the roof is not nailed down.
(II)What is the volume rate of flow of water from a 1.85-cm-diameter faucet if the pressure head is 12.0 m?
