Alarge artery in a person’s body can be approximated by a tube of diameter 9 mm and length 0.35 m. also assume that blood has a viscosity of approximately 4 ×10-3 n-s/m2 , a specific gravity of 1.0, and the pressure at the beginning of the artery is equivalent to 146 mm hg. if the flow were steady with v = 0.2 m/s, determine the pressure at the end of the artery if it is oriented(a) vertically up (flow up) (b) horizontal.
