0.5 m 20 kg A B C p= = 1000 kg T 0.15 m A container of water has a cross-sectional area of 0.50 m². A piston sits on top of the water (see the above figure). A spout is located 0.15 m from the bottom of the tank, open to the atmosphere, and a stream of water exits the spout. The cross-sectional area of the spout is 5.0 x 10-4 m². What is the pressure right under the piston? What is the velocity of the water as it leaves the spout? How far from the spout does the water hit the floor if the tank sits on the floor? Ignore all friction and dissipative forces.

Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
