If a diver goes down 33.0 m (a bit over 100 ft) in the ocean, by how much does each cubic centimeter of her blood change in volume?

(delta)V=(delta)P/BulkMod. * V ???

How deep must a diver go so that each drop of blood compresses to half its volume at the surface?

Is the ocean deep enough to have this effect on the diver?

**drwls**, Wednesday, November 14, 2007 at 11:33pmThe bulk modulus of water is 2.2*10^9 Pa. You omitted some terms. Use the formula which you wrote But with a minus sign) to solve for

(delta V/V). At 33 m depth, the delta P is 33*10^4 Pa

You will find that deltaV/V is a small fraction at this depth.

Then find that delta P needed to make

delta V/V = 1/2, and calculate the corresponing depth.

The deepest spot in the ocean has a depth of about 10,000 m.
