Attached to this homework is a news article from the online financial news site \"MoneyBlog.com\".Notice the highlighted region with ted circles in the article. The article states that the hydrostatic water pressure at the Gulf of Mexico sea floor (5000 feet deep) where the B .P, oil pipe hat broken is about 20,000 pounds per square inch. Is this the correct value for the hydrostatic pressure of water 5,000 ft below the surface? Calculate the gage pressure at 5000 ft and compare it to the article\'s value Assume that the seawater density has a constant value of 1000 kg/m^3 from surface to seabed. FYI: While the actual density varies due to local salinity and temperature, the assumption of constant seawater density is not \"too bad\"...., I found that this approximation results in an error no more than i0% of the actual value. I used the following two references to verify this statement:

Solution

the density of sea water= 1000 kg/m^3= 1.94 lbm/ft^3

gauge pressure= density * gravitational accleration* depth

P= 1.94* 32.2 * 5000 lb/ft^2

P= 312340 lb/ft^2

P= 312340/144 psi= 2169.027778 psi less than 5000 psi.
