Answer
(a) $0.770m$
(b) increased
Work Step by Step
(a) We know that
$h=\frac{P-P_{at}}{\rho g}$
We plug in the known values to obtain:
$h=\frac{109KPa-101.3KPa}{(1020)(9.81)}$
$h=0.770m$
(b) If we use a less dense fluid, then the height must be increased because the density of the fluid is inversely proportional to the height.
