1) During your experiment, you will have air flowing at a constant flow rate through four different sized ports in a chamber as shown in the picture. Cross sectional area Calculate the cross sectional area for port #1 if its dimension are: Width = 7.2160 x 103 m Depth = 8.0260 x 103 m 2) The relationship between Flow Rate (R), Cross Sectional Area (A) and Velocity (v) is called the Continuity equation: R = Av Use the area from question 1 to calculate the velocity of the air at port #1 if the air is m3 flowing at a rate of R= 0.0011366. Width Depth
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.
