In ideal flow, a liquid of density 935 kg/m moves from a horizontal tube of radius 2.00 cm into a second horizontal tube of radius 1.000 cm at the same elevation as the first tube. The pressure differs by AP between the liquid in one tube and the liquid in the second tube. (a) Find the volume flow rate as a function of AP. volume flow rate = mis (b) Evaluate the volume flow rate for AP = 6.80 kPa. L/s (c) Evaluate the volume flow rate for AP = 13.6 kPa. L/s
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.
