Massa especfica = density Profundidade = depth

The graph to the side shows the variation of the specific mass of the sea water along the depth in the Basin Fields, where there are facilities deep and ultra-deep oil extraction from submarine reservoirs. This relationship can be obtained, to a good approximation, by the function p(h)=0.0057 h+1026 where p is the density, in kg/m, and h is the depth in meters. 1) Obtain the expression of the specific weight as a function of depth. Calculate the water pressure at a depth of 2000 m by integrating the basic fluid static equation. 2) What would be the percentage error in the calculation of the previous item if water were considered as an incompressible fluid and the equation: Ap =pgh was used based on the surface density?
