The Science of Fluid Dynamic

1. Incompressible Flow Continuity Equation:
∇ · u is equal to zero.

2. Equations for the Conservation of Momentum (Naumann-Stokes):
The integral of ρ( ∂u/∂t + u · ∇u ) equals negative ∇p plus μ plus ∇²u plus f.

Number of Reynolds: 3.
The value of Re is equal to (ρ * v * L) divided by μ.

Principle of Bernoulli: 4.
p plus half of ρ times v squared plus ρ times gz equals constant

For a long time now, I've been attempting to train new firefighters by explaining fluid dynamics and the problems with pressure versus flow in big fire pumps.
Specifically, in and around mega-sized fire water pumps.
Either they understand immediately or they will never.

No one knows what this has to do with the CHR.

What does the chr have to do with all this nonsense?
