Continuity Equation and Dynamic Pressure
Blood flows through an artery at a speed of 30 cm/s. Due to plaque buildup, the artery constricts to a region where its cross-sectional area is 70% of its original value. By what factor does the dynamic pressure, ½ρv², change in this constricted region?
A
Increases by a factor of 2.04
B
Increases by a factor of 4.08
C
Increases by a factor of 1.43
D
Decreases by a factor of 0.70
