At the surface of the ocean, the water pressure is the same as the air pressure abovethe water, 15 lb/in2. Below the surface, the water pressure increases by 4.34 lb/in2forevery 10 ft of descent.(a) Express the water pressure as a linear function of the depth below the ocean surface.

Answer:

P = P0 + 4.34(x).

X represent the fraction of 12Inch moved down the sea level.

Explanation:

At the surface of the ocean.

Let the surface pressure be P0.

P0 = 15 lb/In².

For every 10ft descent....

Pressure = +4.34 lb/In².

But 1ft = 12 inch

10ft =120 inch.

So for every 12 inch descent

Pressure = + 4.34 Ib/In²

Let the pressure at any Depth be P

P = P0 + 4.34(x).

X represent the fraction of 12Inch moved down the sea level.
