(I) If you tried to smuggle gold bricks by filling your backpack, whose dimensions are 54cm脳 31cm脳 22cm what would its mass be?
The mass of the gold bricks is 710.78Kg.

A copper (Cu) weight is placed on top of a 0.40-kg block of wood (\({\bf{density = 0}}{\bf{.60 \times 1}}{{\bf{0}}^{\bf{3}}}\;{\bf{kg/}}{{\bf{m}}^{\bf{3}}}\) ) floating in water, as shown in Fig. 10鈥�58. What is the mass of the copper if the top of the wood block is exactly at the water鈥檚 surface?

(I)Show that Bernoulli鈥檚 equation reduces to the hydrostatic variation of pressure with depth (Eq. 10-3b) when there is no flow\(\left( {{v_1} = {v_2} = 0} \right)\).
(II)What gauge pressure in the water pipes is necessary if a fire hose is to spray water to a height of 16 m?
(I)How fast does water flow from a hole at the bottom of a very wide, 4.7-m-deep storage tank filled with water? Ignore viscosity.
Water at a gauge pressure of \({\bf{3}}{\bf{.8}}\;{\bf{atm}}\) at street level flows into an office building at a speed of \({\bf{0}}{\bf{.78}}\;{\bf{m/s}}\) through a pipe \({\bf{5}}{\bf{.0}}\;{\bf{cm}}\)in diameter. The pipe tapers down to \({\bf{2}}{\bf{.8}}\;{\bf{cm}}\) in diameter by the top floor, \({\bf{16}}\;{\bf{m}}\) above (Fig. 10鈥�53), where the faucet has been left open. Calculate the flow velocity and the gauge pressure in the pipe on the top floor. Assume no branch pipes and ignore viscosity.
