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.

(a) Using Bernoulli's equation, show that be measured fluid speed v for a pitot tube, like the one in figure 14.32(b), is given by v=( 2gh)1/h , where h is be height of be manometer fluid, p' is the density of the manometer fluid, p is the density of the moving fluid, and g is be acceleration due to gravity. (Note that v is indeed proportional to the square root of h, as stated in text) (b) Calculate v for moving air if a mercury manometer's h is 0.200 m. Figure 14.32 Measurement of fluid speed on Bernoulli’s principle. (a) A manometer is connected to two tubes close together and small enough not to disturb the flow. Tube 1 is open at the end facing the flow. A dead spot having zero speed is created there. Tube 2 has an opening on the side, so the fluid has a speed v across; thus, pressure there drops. The difference in pressure at the manometer is 12v22 , so h is proportional to . 12v22 (b) This type of velocity measuring device is a Prandtl tube, also known as a pitot tube.
