Consider a healthy artery, with blood flow velocity of 0.14m/s and density of 1050kg/m³. Suppose that plaque has narrowed an artery to one-fifth of its normal cross-sectional area (an 80% blockage). Treat the blood as a completely ideal fluid (no viscosity) a) What will be the velocity of the blood through the blockage? b) By how much will the pressure in the blood change as it passes through the blockage?
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.
