If the open-tube manometer in the figure below contains a nonvolatile silicone oil (density = 1.30 g/cm3) instead of mercury (density = 13.6 g/cm3), what are the pressures in the flask as shown in parts a and b in torr, atmospheres, and pascals? (The atmospheric pressure above the tubes is 760. torr.)
Calculate the pressure if ha = 154 mm.
What is the pressure if hb = 240. mm?
