Expert Answer
The density of the sea water is greater than the density of the river water.
The pressure of river water is p1 and density is d1
while pressure of sea water is p2 and density is d2
We know,
p1 = h1 d1 g ...(1)
p2 = h2 d2 g ...(2)
Given: h1 = h2
Thus, dividing equation (1) by (2), we have,
p1/p2 = d1/d2
As, d2>d1
p2>p1
Thus, the relation between the pressure at same depth of river water and sea water is given as,
p2>p1
