## If mercury is used as the liquid, what is the differential pressure being measured?

The liquid in column 2 of a manometer rises 2.25 inches and the liquid in column 1 lowers 2.25 inches. If mercury is used as the liquid, what is the differential pressure being measured? The hydrostatic pressure of 1 square inch of water 100 feet deep is how many psi? If the liquid is ethyl alcohol instead of water, the hydrostatic pressure is how many psi? Suppose a liquid at 60 degrees Fahrenheit has a specific gravity of 6.28. If the measured pressure at the bottom of the tank in which it is stored is 51.3 psi, what is the height of the liquid?
