Amanometer that is filled with water (rho=1000 kg/m3) is connected to a wind tunnel to measure the pressure inside the test section. the other manometer is open to the atmosphere and the atmospheric pressure is 100 kpa. the difference in the manometer level is 100 mm. determine the absolute pressure in the test section in kpa.

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a.water evaporates, which favors the formation of h2co3. b.pressure decreases, which favors the formation of h2co3. c.the open container warms up, which causes more gas to escape. d.co2is removed, which favors the formation of h2co3.
