Water is pumped through a pipe of diameter 15.0cm from the Colorado River up to Grand Canyon Village on the rim of the canyon. The river is at 564m elevation and the village is at 2 096 in(a) At What minimum pressure must the water be pumped to arrive at the village? b) If 4500 m3 are pumped per day what is the speed of the water in the pipe? (c) What additional pressure is necessary to deliver this flow? Note you may assume the free- fall acceleration and the density of air are constant over the given range of elevations.
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.
