A U -tube in which the cross-sectional area of the limb on the left is one-third of the limb on the right contains mercury (density 13.6 g//cm^(3) ). The level of mercury in the narrow limb extends to a distance of 30 cm from the upper end of the tube. What will be the rise in the level of mercury in the right limb, if the left limb is filled to the top with water (neglect surface tension effects)?

Mercury is poured into a U-tube in which the cross-sectional area of the left-hand limb is three times smaller than that of the right one. The level of the mercury in the narrow limb is a distandce l=30 cm from the upper end of the tube. How much will the mercury level rise in the right-hand limb if the left one is filled to the top with water?

  • Arrange the following steps in proper sequence to determine the pressure exerted by a gas enclosed in a container using a manometer. (a)Connect one end of the manometer to the container filled with gas. (b)Both the limbs of the manometer are exposed to air, mercury level in both the limbs are equal due to atmospheric pressure. (c )Determine the difference in level of the mercury in both the limbs of the manometer (l). (d) If the level of the mercury in the limb connected to the container is above the mercury level in the limb exposed to air, the pressure of the gas in the container is determined as atmospheric pressure -l. (e ) If the level of the mercury in the limb connected to the container is below the mercury level in the limb exposed to air, the pressure of the gas in the container is determined as atmospheric pressure +l. (f) Note the level of the mercury in the limbs of the manometer.
