A U tube contains water and methylated spirit seperated by mercury .The mercury columns in the two arms at the same level with 10 cm of water in one arm and 12.5 cm of spirit in the order as shown in figure. The relative density of the spirit is

Text Solution

Verified by Experts

The correct Answer is:
` 0.8 `
Pressure exerted by spirit = pressure exerted by water `(hrhog) 12.5 x10 ^(-2) xx rho _s g = 10 xx 10 ^(-2) xx 1000 g. rho _s = 0.8 xx 10 ^(3) kg m ^(-3) , R.D .= 0. 8`

The velocity head of a stream of water is equal to 20 cm of mercury column. What is the velocity of flow in the stream ? The relative density of mercury is 13.6. (g = 9.8 ms^(-2))

In a constant volume gas thermometer, the pressure of the working gas is measured by the difference in the levels of mercury in the two arms of a U-tube connected to the gas at one end. When the bulb is placed at the room temperature 27.0^0 C , the mercury column in the arm open to atmosphere stands 5.00 cm above the level of mercury in the other arm. When the bulb is placed in a hot liquid, the difference of mercury levels becomes 45.0 cm . Calculate the temperature of the liquid. (Atmospheric pressure = 75.0cm of mercury).

A piece of wood of uniform cross section and height 15 cm floats vertically with its height 10 cm in water and 12 cm in spirit. Find the density of (i) wood and (ii) spirit

The arms of a U shaped tube are vertical. The arm on right side is closed and other arm is closed by light movable piston. There is mercury in the tube and initially the level of the mercury in the arms is the same. Above the mercury, there is an air column of height h in each arm, and initial pressure is the same as atmospheric pressure in both arms. Now pistion is slowly pushed down by a distance of h//2 (see figure) Let x is the displacement of mercury level in one of the stem and P_(1) is pressure in left column of air after compression, P_(2) is pressure in right column of air after compression and P_(0) is atmospheric pressure then
