PRESSURE DEPTH RELATIONSHIP P/ z= - g (P 2 – P 1 ) = - g (z 2 -z 1 ) How can we use the above eq to find pressure at some depth? Classroom problem Thresher sank in Atlantic in 1963. The sea level where this accident had occurred was at 1000 ft. What was the pressure of sea at 1000 ft? density of sea water: 63.9 lbm/ft^3
