) A long, small diameter tube is shown below. The top end of the tube is closed. The bottom end is open and immersed in a pool of liquid mercury. The free surface of the mercury pool is exposed to atmospheric pressure, Patm =1 atm. The tube is filled with a column of oil and a column of water. A volume of gas is trapped at the top of the tube. The distance from the mercury free surface to the oil-water interface is LI = 20 in. The distance from the oil-water interface to the water-gas interface is L2= 10 in. The density of water pu, oil po, PHg are 62.3 lbm /ft', 57 lbm ft', and 847 lbm/ft', respectively. Determine the gas pressure in the units given below: and mercury a) absolute b) vacuum pressure [psi (vac)], and c) gage pressure [psig]. pressure [psia] and [kPa (abs)]
