Pressure at Depth (3, 1)

This equation describes hydrostatic pressure for an incompressible fluid. Depth h is positive downwards from the reference.

Equation:

P = P0 +ρ ⋅ g ⋅ h

Example:

Given: h=100_m, ρ=1025.1817_kg/m^3, P0=1_atm.

Solution: P=1106.6848_kPa.

Bernoulli Equation (3, 2)

These equations represent the streamlined flow of an incompressible fluid.
