An engineer decided to use an old tank to store a salty solution of(NH4)2SO4. At the side of the tank, 20 cm from the bottom, there is amanometer "Open End" type. The height in the left arm (d1) is 10 cmbelow the connection to the tank (see drawing I), and the mercury densityis 13.59 𝑔𝑚𝑐𝑚3. The engineer started to fill the tank at a rate of 11.1 𝐾𝑔𝑚𝑖𝑛 .During the first 17 min the reading of the manometer was zero, and afterthat the mercury on the right arm of the manometer started to rise. Whenthe liquid in the tank arrived at a height of 100 cm from the bottom, themanometer reading (hHg) was 87 mm Hg, as shown in drawing II.a. Calculate the solution concentration (in molar units)b. What is the tank diameter (in m)?

You are working with a triple sealed tank with pressure gauges that measure the pressure inside each tank. The gauges report the gauge pressure inside each tank with respect to the pressure in the tank surrounding it. A mercury manometer is connected to the inner most tank, and the other end to the manometer is connected to the atmosphere. All three gauges read -20kPa. What is the reading height of the manometer fluid in mmHg? Please note 1 mmHg = 133.3 Pa)

A manometer attached to pressurized nitrogen tank reads 710 mm of mercury. If the atmospheric pressure is 101 kPa, what is the absolute pressure in the tank? The density of mercury is 13,600 kg/m3.

Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A1 of 10.9 cm2, and the right arm has a cross-sectional area A2 of 5.20 cm2. Two hundred grams of water are then poured into the right arm as shown in Figure b.Figure (a) shows a U-shaped tube filled with mercury. Both arms of the U-shaped tube are vertical. The left arm with cross-sectional area A1 is wider than the right arm with cross-sectional area A2. The height of the mercury is the same in both arms. Figure (b) shows the same U-shaped tube, but now most of the right arm is filled with water. The height of the column of water in the right arm is much greater than the height of the column of mercury in the left arm. The height of the mercury in the left arm is greater than the height of the mercury in the arms in Figure (a), and the difference in height is labeled h.(a) Determine the length of the water column in the right arm of the U-tube. cm(b) Given that the density of mercury is 13.6 g/cm3, what distance h does the mercury rise in the left arm? Your response differs from the correct answer by more than 100%. cm

A mercury manometer measures a pressure of 200 mmHg. What is this pressure in atm?

a piston in a cylinder that is connected to a manometer. describe and explain what will happen to the difference in height between the two mercury level when more mercury is poured into the manometer, when the initial difference is 0.2 m
