As the heart beats, blood pressure in an artery varies from a high of 125 mm of mercury
Chapter 18, Problem 33(choose chapter or problem)
As the heart beats, blood pressure in an artery varies from a high of 125 mm of mercury to a low of 80 mm. These values are gauge pressuresthat is, excesses over atmospheric pressure. An air bubble trapped in an artery has diameter 1.52 mm when blood pressure is at its minimum. (a) What will its diameter be at maximum pressure? (b) How much work does the blood (and ultimately the heart) do in compressing this bubble, assuming the air remains at the same temperature as the blood?
