A U-tube manometer containing a light oil (specific gravity 0.7) is used to measure the static pressure of air (density 1.2 kg/m³) in a container. If the gauge pressure is 206 N/m², what is the indicated height of oil?

A pressure sensor is used to measure the level of a liquid in a tank. The weight density of the liquid is 6000 N/m3. If the gauge pressure (from the sensor) is 12,000 Pa. What is the height of the liquid?

Consider the sealed containers (same fluid and on the same ground level) below with heights given in ? and ? values.Provided that ? = 2?, answer the following items. (refer to a.jpg) What container has the greatest pressure at the point indicated?  Which point experiences the least pressure?  Suppose the bottom pressure is evaluated, what container experiences the second highest pressure?

If the atmospheric pressure is 1.01325 bar, what will be the height of the mercury column in a barometer? The density of mercury is 13600 kg/m3.
