Under Normal situations the viscosity of a person's blood is about 3.8 x 10' Pa s. When that person is dehydrated, the viscosity of their blood increases to 4.3 x 10 Pa s. By what factor does the pressure difference across their blood vessels need to increase when the person is dehydrated in order to keep blood flowing the same speed as when they are well hydrated? Assume all other factors of the blood and vessels are in the same in both cases. a. The pressure difference needs to increase by a factor of 1.06 when the person is dehydrated b. The pressure difference needs to increase by a factor of 1.13 when the person is dehydrated c. The pressure difference needs to increase by a factor of 1.28 when the person is dehydrated d. It is impossible to say without knowing the radius or cross-sectional area of the vessels e. It is impossible to say without knowing the speed of the blood flow.
