Engineering Fluid Dynamics: Proof of the Static Pressure Head equation

AI Thread Summary
The discussion focuses on proving the Static Pressure Head equation, H = p/ρg, emphasizing the relationship between pressure (p), density (ρ), and gravitational acceleration (g). Participants highlight that pressure and height are dimensionally compatible due to the roles of density and gravity. The conservation of energy is suggested as a method for deriving the equation, referencing Bernoulli's principle for further insights. The conversation aims to clarify how these variables interact within fluid dynamics. Understanding this relationship is crucial for applications in engineering and physics.

Homework Statement
A horizontal pipe is filled with liquid. When the liquid is stationary, its head H metres depends on the pressure p of the liquid, its density ρ and gravitational acceleration g. Determine the nature of the relationship of these variables.
Relevant Equations
H = p/ρg

Where:
H = Head
p = Pressure
ρ = density
g = gravitational acceleration
I am trying to mathematically prove the Static Pressure Head equation:

H = p/ρg

How can I prove this equation and thus determine the nature of the relationship between these variables?

P (N/m2) and H (m) are equivalent magnitudes.
Rho and g make those two dimensionally compatible.
