We learned that Reynolds number is given where ρρ, vavvav and ηη are the density, average speed and viscosity of the fluid, and DD is the diameter of the channel. The viscousity of blood at normal body temperature is 3.0×10−3 Pa⋅sPa⋅s and the density is 1060 kg/m3kg/m3 . In order to figure out if the blood flow is laminar or turbulent, we need to determine the diameter and the average blood flow speed. we measured the radius of the aorta to be 0.50 cmcm and the average blood flow rate in the aorta to be 6.5×10−4 m3/sm3/s , what then is average fluid velocity vavvav flowing in the aorta?
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.
