1. Butyl carbitol, used in the production of plastics, is stored in a tank having a U-tube manometer. If the
U-tube is filled with mercury, determine the pressure in the tank at point B. Take sgHg = 13.55, and sgbc
= 0.957.
2. The funnel is filled with oil and water to the levels shown. Determine the depth of oil h’ that must be
in the funnel so that the water remains at a depth C, and the mercury level made h = 0.8 m. Take poil =
900 kg/m3, pw = 1000 kg/m3, pHg = 13550 kg/m3.
3. Determine the difference in pressure PB – PA between the centers A and B of the pipes, which are
filled with water. The mercury in the inclined-tube manometer has the level shown SGHg = 13.55.
4. In the figure, pipe A contains gasoline (sg=0.7), pipe B contains oil (sg=0.9), and the manometer fluid
is mercury. Determine the new differential reading if the pressure in pipe A is decreased 25 kPa, and the
pressure in pipe B remains constant. The initial differential reading is 0.30 m as shown.
