Water is pumped into a pipe at 5 times atmospheric pressure. (Strictly speaking, this is the pressure at point P). The water eventually exits from the right end of the pipe into the air. The pipe consists of two cylindrical sections. The radius of the wider section is R=20.0 cm, and the radius of the narrower section is r= 10.0 cm. Both sections have a length of L (see image). The transition between the two segments is very short and can be neglected. 25.0m 25.0 ground A. Consider a water droplet that enters the left end of the pipe in a straight line at time t = 0.

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.

Transcribed Image Text:Problem 3
Water is pumped into a pipe at 5 times atmospheric
pressure. (Strictly speaking, this is the pressure at
point P). The water eventually exits from the right
end of the pipe into the air. The pipe consists of
two cylindrical sections. The radius of the wider
section is R = 20.0 cm, and the radius of the
narrower section is r = 10.0 cm. Both sections have a length of L (see image). The transition between the two
segments is very short and can be neglected.
