Concept explainers

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 medical technician is trying to determine what percentage of a patient's artery is blocked by plaque. To do this, she measured the blood pressure just before the region of blockage and finds that it is 1.20 × 104 Pa, while in the region of blockage it is 1.15 x 104 Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is travelling at 30.0 cm/s. What percentage of the cross-sectional area of the patient's artery is blocked by the plaque?

Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.525 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05×103 kg/m3 a. Calculate the systolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the top (and greater) number is the systolic pressure. b. Calculate the diastolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the bottom (smaller) number is the diastolic pressure.
