Water emerges straight down from a faucet with a1.80-cm diameter at a speed of 0.500 m/s. (Because of theconstruction of the faucet, there is no variation in speedacross the stream.) (a) What is the flow rate in cm3 /s ? (b)What is the diameter of the stream 0.200 m below the faucet?Neglect any effects due to surface tension.
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.
