Under control conditions, flow through a blood vessel is 100 ml/min with a pressure gradient of 50 mm hg. what would be the approximate flow through the vessel after increasing the vessel diameter by 100%, assuming the pressure gradient is maintained at 50 mmhg?

flow = 1600 ml/min

Hi!

This problem si solved using Poiseuille law, which predicts the flow φ of a viscous fluid through a tube:

We can calculate the ratio of initial (1) and final (2) flow. As we keep the same length, and viscosity, and pressure gradient the ratio is:

  (100% increase in radius)

= 1600 ml/min

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
