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 5.24 mm of the vessel moving with speed. (See in the following figure.(Eigure 1)) Figure X XBX X X X X X X X d 1 of 1
Y Part A If the blood vessel is placed in a magnetic field B perpendicular to the vessel, as in the figure, determine th motional potential difference & induced across it. Express your answer in terms of some or all of the variables B, d, and v. ε = Submit ▾ Part B 195| ΑΣΦ B = Request Answer If you expect that the blood will be flowing at 15.1 cm/s for a vessel 5.24 mm in diameter, what strength of magnetic field will you need to produce a potential difference of 1.00 mV ? Express your answer with the appropriate units. == HA Value Submit Request Answer Units BENE ? ?
Part C 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.)
