When a mercury manometer is connected to a gas main, the mercury stands 45.0 cm higher in the tube that is open to the air than in the tube connected to the gas main. A barometer at the same location reads 79.0 cm Hg. Determine the absolute pressure of the gas in cm Hg.

Find the gauge and absolute pressures in the balloon and peanut jar shown in Figure 11.16, assuming the manometer connected to the balloon uses water whereas the manometer connected to the jar contains mercury. Express in units of centimeters of water for the balloon and millimeters of mercury for the jar, taking h=0.0500h=0.0500 m for each.

Figure 11.16 An open-tube manometer has one side open to the atmosphere. (a) Fluid depth must be the same on both sides, or the pressure each side exerts at the bottom will be unequal and there will be flow from the deeper side. (b) A positive gauge pressure Pg=hρgPg=hρg transmitted to one side of the manometer can support a column of fluid of height h. (c) Similarly, atmospheric pressure is greater than a negative gauge pressure PgPg by an amount hρghρg .The jar's rigidity prevents atmospheric pressure from being transmitted to the peanuts.

A mercury manometer is connected to an air duct to measure the pressure inside. The difference in the manometer levels is , and the atmospheric pressure is . (a) Judging from Fig. P2–56, determine if the pressure in the duct is above or below the atmospheric pressure. (b) Determine the absolute pressure in the duct. 

A sphygmomanometer is a device used to measure blood pressure, typically consisting of an inflatable cuff and a manometer used to measure air pressure in the cuff. In a mercury sphygmomanometer, blood pressure is related to the difference in heights between two columns of mercury.

The mercury sphygmomanometer shown in Figure P9.15 contains air at the cuff pressure P. The difference in mercury heights between the left tube and the right tube is h = 115 mmHg = 0.115 m, a normal systolic reading. What is the gauge systolic blood pressure Pgauge in pascals? The density of mercury is p = 13.6 × 103 kg/m3 and the ambient pressure is P0 = 1.01 × 105 Pa.
