The liquid flowing through a pipe of diameter 3 cm flows into a constriction of diameter 1 cm. A pressure gauge at the constricted section and at the main pipe shows that the pressure at the constricted part is smaller by 8 000 dynes/cm2 than the pressure at the main pipe. Find (a) the velocity (in cm/s) of the liquid in the main pipe and in the constriction, and (b) the rate of flow of the liquid through the pipe
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.
