Answer
Answer:
A). Please see the image.
B.) depth d = 34 ft.
Work Step by Step
Here P = 14.7 + 0.45d
P is presuure in $\frac{lb}{in^{2}}$, d is depth in feet.
A). we get answer by using values of depth d as 0, 10, 20, 30, 40, 50, 60.
B.) Here P = 30 $\frac{lb}{in^{2}}$
d = $\frac{P - 14.7}{0.45}$ = $\frac{30 - 14.7}{0.45}$ = $\frac{15.3}{0.45}$ = 34 ft
