Deriving the pressure equation $\Delta p = \rho g \Delta h$ involves several relationships between quantities. Which relationship is not included in the derivation of this equation?
- Adensity = $\frac{\text{mass}}{\text{volume}}$
- Bpotential energy = mass $\times$ acceleration of free fall $\times$ height
- Cpressure = $\frac{\text{force}}{\text{area}}$
- Dweight = mass $\times$ acceleration of free fall
