Is there any dependence of pressure on height/depth from sea level? ?
Yes. The variation of pressure in a fluid at different height is due to gravity and is called hydrostatic pressure. It is defined as:
p - p0 = rho * g * h
h = z - z0 is the height from the reference point 0 (arbitrary)
p0 is the pressure at reference point 0
rho is the fluid density
g is the gravity (assumed constant)
BTW if you are interested, check out this free course by Ansys, that talks about Fluid Statics in detail:
