A manometer tube contains mercury of density `13.6 xx 10^(3)` kg `m^(-3)`. What difference in the levels of mercury in the two arms is indicated by a gauge pressure of `1.03 xx 10^(5) Pa`?

A manometer tube contains a liquid of density 4xx10^(3) kg m^(-3) . When connected to a vessel containing a gas, the liquid level in the other arm of the tube is higher by 20 cm. When connected to another sample of enclosed gas, the liquid level in the other arm of the manometer tube falls 8 cm below the liquid level in the first arm. Which of the two samples exerts more pressure and by what amount ?

If 15.0 cm of water and spirit each are further poured into the respective arms of the tube, what is the difference in the levels of mercury in the two arms? (Relative density of mercury = 13.6).

Glycerine flows steadily through a horizontal tube of length 1.5m and radius 1.0 cm. If the amount of glycerine collected per second at one end is 4. 0 xx 10^(-3) kg s^(-1) what is the pressure difference between the two ends of the tube? (Density of glycerine = 1.3 xx 10^(3) kg m^(-3) and coefficient of viscosity of glycerine = 0.83 Ns m^(-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).

Water rises to a height of 9cm in a certain capillary tube. In the same tube the level of mercury surface is depressed by 3 cm . Compute the ratio of surface tension of water and mercury . Density of mercury 13.6 xx 10^(3) kg m^(-3) . Angle of contact of water is zero and that for mercury is 135^(@) .

A u tube contains water and methylated spirit separated by mercury. The mercury columns in the two arms are at the same levels with 10 cm of water in one arm and 12.5 cm of spirit on the other arm as shown. If 15 cm of water and spirit each are further poured into the respective arms of the tube. Difference in the level of mercury in the two arms is (Take, relative density of mercury = 13.6, relative density of spirit=0.8)
