The water circulates throughout the building in a hot water heating system. If the water is pumped at a speed of 1 m/s through a 6 cm diameter pipe in the basement under a pressure of 200 kPa, a. what will be the velocity and pressure in a 3 cm diameter pipe on the 2nd floor that is 5 m above the basement? b. from basement to 2nd floor, what happens to the speed of the water? c. from basement to 2nd floor, what happens to the pressure of the water?
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.
