Extracted text: 4. A manometer (pressure-measuring device) uses kerosene (sg=0.82) as the fluid. A reading of 5 inches on the kerosene manometer is equivalent to how many millimeters of mercury (sg=13.6) in a mercury manometer? Solution: We determine the pressure at the base of the 5-in kerosene column. This is also the same pressure at the base of the mercury column. Using the definition of the head, we compute for the height of mercury column (in mm) using the pressure we obtained earlier. P = (pgH)kerosene P Hug - (pg)Hg %3D HH9 7.6574 mm Hg %3!
