(a) for a nonsmoker, with blood viscosity of 2.50 10-3 pa·s, normal blood flow requires a pressure difference of 8 mm hg between the two ends of a certain artery. if this person were to smoke regularly, his blood viscosity could increase to 2.80 10-3 pa·s (a 12% increase), and the diameter of his artery would constrict by 11%. what pressure difference between the ends of the artery would then be needed to maintain the same blood flow rate? mm of hg

13.6565mm of Hg

Explanation:

We only need to use the from Hagen poiseuille equation to be able to find the pressure change.  That is

Once the equation is defined, we clear based on the pressure and replace

Finally we have,

i think the answer is a and b

i wish you luck

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
