Chapter 1.1, Problem 9E

(Oceanography) The pressure, P, exerted on an underwater object can be determined by this
formula:

$P=\rho \times g\times h$

ρ is the density of water, which is $1.94{\text{ slug/ft}}^{\text{3}}$ .

g is the acceleration caused by Earth’s gravity, which is $32.2{\text{ ft/sec}}^{\text{2}}.$

h is the object’s depth in the water in feet.

a. Determine the units of P by calculating the units resulting from the right side of the formula.
Check that your answer corresponds to the units for pressure listed in Table 1.1.
b. Determine the pressure on a submarine operating at a depth of 2500 feet.
