(a)
Fluid pressure is a measurement of the force per unit area on an object in the fluid or on the
surface of a closed or open tank. In industrial or laboratory applications, a standpipe
containing a static liquid is being used in creating a stable pressure on a particular process
or system. The tank shown in the Figure 2 holds oil of specific gravity 0.89. The top of the
tank is closed and the space in the tank above the oil contains air. The U-tube manometer
contains water and the displacements are as indicated. Atmospheric pressure is 101.3 kPa.
