You have a garden hose with a 410 kPa supply of water from the faucet. The hose is 8 meters long, .012 m in diameter, and has a flow rate of 0.0015 m3/second. Prove that you do (or don’t) need to consider viscosity by determining the pressure associated with pushing viscous water (0.001 Pa.s) through the full length of the hose and compare that pressure to the supply pressure.
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.
