L The Poiseuille's law for flow through a cylindrical pipe (blood vessel) is: K =(R²-2²), where v is the velocity, K is a constant equal to 6 1/s, L is the length of the pipe, R is the radius of the pipe and r is the distance out from the center line of the pipe. For a 100-cm pipe of radius 0.2 cm, find the rate that the flow velocity is changing half-way between the center line and the wall when the pipe is contracting at a rate of 0.0004 cm/s?

L
The Poiseuille's law for flow through a cylindrical pipe (blood vessel) is:
K
=(R²-2²), where v is the velocity, K is a constant equal to 6 1/s, L is
the length of the pipe, R is the radius of the pipe and r is the distance out
from the center line of the pipe. For a 100-cm pipe of radius 0.2 cm, find the
rate that the flow velocity is changing half-way between the center line and
the wall when the pipe is contracting at a rate of 0.0004 cm/s?
