a. Oil with S = 0.86 is being transported in a pipe. Calculate the pressure if a U-tube manometer reads 9.5 in. Hg. The oil in the manometer is depressed 5 in. below the pipe centerline.
b. Several liquids are layered inside a tank with pressurized air at the top. If the air pressure is 3.2 kPa, calculate the pressure at the bottom of the tank if the layers include 20 cm of SAE 10 oil, 10 cm of water, 15 cm of glycerin, and 18 cm of carbon tetrachloride.
