The Flow Rate of a Fluid Is Expressed as a Velocity

question 34

Multiple Choice

The flow rate of a fluid is expressed as a velocity of fluid multiplied by the cross-sectional area of the pipe (vA) . Assume that the pipe is a blood vessel with circular cross-sectional area calculated as A = ðr², where r is radius. In a continuous flow rate, where v₁A₁ = v₂A₂, what is the change of the velocity of blood if a blood vessel with radius r₁ reduced its radius by a factor of 2 to r₂ = r₁/2?

• A)v₂ = (1/4)v₁
• B)v₂ = 2v₁
• C)v₂ = 4v₁
• D)v₂ = (1/2)v₁
