The reading on a mercury manometer at 70(°F) (open to the atmosphere at one end) is 25.62(in). The local

What will be an ideal response?


The total pressure is equal to atmospheric pressure plus the weight per area of the mercury column. The

only trick is to do this in the non-SI units given. Let us compute the pressure in psia (pounds-force per square inch, absolute). To do so, we should convert the density of mercury from Thus, We also need to convert atmospheric pressure from in Hg to psia by multiplying by 0.4912 psi/(in Hg).

So,
