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 pressur we obtained earlier. P = (pgH)kerosene P Hug - (pg)Hg %3D HH9 7.6574 mm Hg %3!

Transcribed Image 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.
