Be sure to review Examples 12.7, 12.8, and 12.9 (Section 12.5) before attempting these problems. The storage tank in the figure below contains ethanol (density 8.1 x 10 kg/m). The tank is 4.0 m in radius, the short pipe at the bottom of he AR 1.0 cm in radius, and the height of ethanol in the tank is 3.2 m. The volume flow rate of ethanol from the short pipe is 4.4 x 10 m /s -Po R=4.0 m h = 3,2 m FR = 1.0 cm 2 Patm What is the speed at which ethanol flows out of the short pipe? Express your answer with the appropriate units.

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.
