(See Fluids in the News article titled “Giraffe’s blood pressure,” Section 2.3.1.) (a) Determine the change in hydrostatic pressure in a giraffe’s head as it lowers its head from eating leaves 6 m above the ground to getting a drink of water at ground level as shown in Fig. P2.11. Assume the specific gravity of blood is SG=1. (b) Compare the pressure change calculated in part (a) to the normal 120 mm of mercury pressure in ahuman’s heart.
