Whats the pressure at 1500 ft under water?

Question

as in pressure per sq ft also whats the air pressuer at sea level.

Answer 1

the weight of a 1ft square column of water 1500ft high + airpressure at 15lbs/sq in which is about 0.1 lb/sq ft

Sorry I don't do old fashioned non-metric measurements.

Answer 2

700 psi

Answer 3

1500*62.4 = 93600 lb/ft²

2116 lb/ft² (handbook value)

Answer 4

The density of sea water is 64.1 lbs/cu ft      so ;

64.1 lbs/ft^3* 1500 ft  =  96150 lbs/ft^2

Now we add the atmospheric pressure at sea level (which is

2116.8 lbs/ft*2 , rounded to 4 sig figs = 2117)

96150 lbs/ft^2 + 2,117 lbs /ft^2 = 98267 lbs/ft^2

Steve looks to have the answer for the case of fresh water.

Answer 5

In my reference book, sea water weighs 64.3 lb/ft^3, so I got 96450 lbs/ft^2, or 669.79 psi.
