Air at 20∘C flows through the tube shown in (Figure 1). Assume that air is an ideal fluid. The density of air is 1.20 kg/m3, the density of mercury is 13600 kg/m3. Suppose that d1 = 3.00 mm and d2 = 1.20 cm . a) What is the air speed v1at point 1? Express your answer with the appropriate units. b)What is the air speed v2 at point 2? c) What is the volume flow rate?
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.

a) What is the air speed v1at point 1? Express your answer with the appropriate units.
b)What is the air speed v2 at point 2?
c) What is the volume flow rate?
Given that:
Density of air = 1.2 kg/m3
Density of mercury = 13600 kg/m3
d1 = 3.00 mm and d2 = 1.20 cm
d1=3 X 10-3 m and d2=1.2 X 10-2 m
temperature = 20o C
