(a) What is the largest average velocity of blood flow in an artery of radius `2xx10^(-3)m` if the flow must remian laminar?
(b) What is the corresponding flow rate? Take viscosity of blood to be `2.084xx10^(-3)Pa-s`. Density of blood is `1.06xx10^(3)kg//m^(3)`.

A

0.75 m/s

B

0.82 m/s

C

0.98 m/s

D

1.2 m/s

Text Solution

Verified by Experts

The correct Answer is:
D
The critical velocity or maximum average velocity for laminar streamline flow is give by
`v_c=(etaR)/(rhoD)=(2.084xx10^(-3)xx2000)/(1.06xx10^3xx4xx10^(-3))`
`=(4.168)/(4.24)=0.98m//s`
