(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)`.

Explanation

To solve the problem, we will break it down into two parts as given in the question.

### Part (a): Finding the Largest Average Velocity of Blood Flow

1. **Given Data**:
- Radius of the artery, \( r = 2 \times 10^{-3} \, \text{m} \)
- Viscosity of blood, \( \mu = 2.084 \times 10^{-3} \, \text{Pa.s} \)
- Density of blood, \( \rho = 1.06 \times 10^{3} \, \text{kg/m}^{3} \)
