Measuring Blood Flow. Blood contains positive and negative
ions and thus is a conductor. A blood vessel, therefore, can
be viewed as an electrical wire. We can even picture the
flowing blood as a series of parallel conducting slabs whose
thickness is the diameter 5.00 mm of the vessel moving with
speed. (See in the following figure.(Figure 1))

Determine the volume rate of flow (R). (Note: Although the method developed here is useful in measuring the rate of blood flow in a vessel, it is limited
to use in surgery because measurement of the potential & must be made directly across the vessel.)
