A U-tube of uniform cross-sectional area and open to the atmosphere is partially filled with mercury. Water is then poured into both arms. If the equilibrium configuration of the tube is as shown in figure with `h_(2)=1.0cm`, determine the value of `h_(1)`
.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`p_(1)=p_(2)`

` :. p_(0)+rho_(w)g (h_(1)+h_(2)+h)=p_(0)+rho_(w)gh+rho_(Hg)gh_(2)`
`:. h-1=((rho_(hg)-rho_(w))h_(2))/(rho_w)`
`=((13.6-1)(1.0))/(1)`
`=12.6 cm`.

A U-tube of uniform cross section (see figure) is partially filled with a liquid I. Another liquid II which does not mix with liquid I is poured into one side. It is found that the liquid levels of the two sides of the tube are the same, while the level of liquid I has risen by 2cm. If the specific gravity of liquid I is 1.1, the specific gravity of liquid II must be

A U-tube with both ends open to the atmosphere is partially filled with water. Oil, which is immiscible with water. Is poured into one side until it stands at a distance of 10 mm above the water level on the other side. Meanwhile the water rises by 65mm from its original level (see diagram). The density of the oil is:

A tube of uniform cross section is used to siphon water from a vessel V as shown in the figure. The pressure over the open end of water in the vessel is atmospheric pressure (P_(0)) . The height of the tube above and below the water level in the vessel are h_(1) and h_(2) , respectively. Given h_(1) = h_(2) = 3.0 m , the gauge pressure of water in the highest level CD of the tube will be
