Pressure at Depth (3, 1)

This equation describes hydrostatic pressure for an incompressible fluid. Depth h is positive downwards from
the reference.
Equation:
P
Example:
Given: h=100_m, =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.
= P 0 + g h
