Solve the first page (2) using the second picture 

The figure A1(b) shows the pressure difference between two pipes, each containing
a liquid of density = 1000 kg/m³, which it is measured using a manometer and is
found to be 42 kN/m². Given that the liquid in the manometer is mercury and that a
=1.5m and b=0.7m

The figure A1(a) shows the pressure of a gas that it is measured by use of a
manometer The manometer liquid is water and h, =0.56 m. The reading on a
nearby barometer is 0.78m of mercury. The density of mercury is 13.6x103
kg/m3.
Calculate:
a) The atmospheric pressure expressed in N/m?.
b) The absolute gas pressure (p) expressed in N/m?.
