In april 2010, the worst oil spill ever recorded occurred when an explosion and fire on the deepwater horizon oil-drilling rig left 11 workers dead and began releasing oil into the gulf of mexico. one of the attempts to contain the spill involved pumping drilling mud into the well to balance the pressure of the escaping oil against a column of fluid (the mud) having a density significantly higher than those of seawater and oil. in the following problems, you may assume that seawater has a specific gravity of 1.03 and that the subsea wellhead was 5024 feet below the surface of the gulf. part a) estimate the gauge pressure (psig) in the gulf at a depth of 5024 feet. part b) the pressure inside the wellhead is 4400 psig. suppose a pipe between the surface of the gulf and the wellhead is filled with drilling mud and balances that pressure. estimate the specific gravity of the drilling mud. part c) drilling mud is a stable slurry of seawater an
