Water Pressure and Pressure Forces - Pearson

The pressure at points 1 and 2 must be the same since the system is in static equilibrium. Step 3. (a) For open manometers, the pressure on 2 is exerted by the weight of the liquid M column above 2; and the pressure on 1 is exerted by the weight of the col-umn of water above 1 plus the pressure in vessel A. The pressures must be equal in value.
