**Question **# 9) At a depth of 4 miles in the ocean the pressure is 9520 psia (absolute pressure).Assume that the specific weight at the surface is 64.00 lb/ft3 and that the average volume modulus is 320,000 psi for that pressure range. (a) What will be the change in density at that depth? (b) What will be the specific volume at that depth? (c) What will be the specific weight at that depth? (d) What is the percentage change in the specific weight?
