I'm not sure how to approach this problem. A manometer uses kerosene, specific gravity 0.82 as the fluid. A reading of 5 inches on the manometer is equivalent to how many millimeters of mercury?

pressure = density*g*height
5" = 5*25.4 mm = h in mm
p = 0.82 x 9.8 x 5 x 25.4 = ? Pa.
Divide by 1000 to convert to kPa.
Then ?kPa x (1 atm/101.325) x (760 mm/1 atm) = ? mm pressure.
Here is a good site for pressure of fluids.
