Problem $1(25$ points$)$

After a long walk on the Serengeti, a giraffe stops for a drink of water. The specific gravity of

the giraffe's blood is $1\mathrm{.}08.$

$SG=1\mathrm{.}0$

A$.$ Calculate the density $($slugs$/($:$f{t}^3\}$ and specific weight $(l\frac{b}{f}{t}^3)$ of the giraffe's blood. $(10$

B$.$ Determine the change in $($hydrostatic$)$ pressure in the giraffe's head as it lowers its head

$6$ m to reach a watering hole. Express your answer in psi. $(10$ points$)$

Calculare the force bait cie gasoline exerts on the gute $($ N $).$ What is the lucation of this

C$.$ The pressure in a human's heart is $2\mathrm{.}3$ psi $.$ How many times greater $($or smaller$)$ is the

pressure change calculated in Part B compared to the pressure in a human's heart? $(5$
