Viscosity and Laminar Flow; Poiseuille’s Law (Problem 33)

A small artery has a length of $1.1\times {10}^{-3}\text{m}$ and a radius of $2.5\times {10}^{-5}\text{m}$. If the pressure drop across the artery is 1.3 kPa, what is the flow rate through the artery? (Assume that the temperature is $\text{ 37º C }$.)
