Solve the problem.The flow of blood in a blood vessel is faster toward the center of the vessel and slower toward the outside. The speed of the blood is given by src="https://sciemce.com/media/4/ppg__tttt0530190837__f1q17g3.jpg" alt="" style="vertical-align: -23.0px;" /> Find Q for a blood vessel of radius R = 1.2 mm.
where R is the radius of the blood vessel, r is the distance of the flowing blood from the center of the blood vessel, and p, v, and L are physical constants related to the pressure and viscosity of the blood and the length of the blood vessel. If R is constant, we can think of V as a function of r:
