A water pipe has a 3.0 cm inside diameter and carries water into the basement of a house. At the basement, the water speed is 1.20 ms−1 and the pressure exerted is 190 kPa. The pipe then tapers to 1.5 cm inside diameter as it rises to the second floor, which is 8.5 m above the input point. Calculate: a) the speed of the water on the second floor. b) the water pressure on the second floor
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.
