Problem
Two students propose expressions for the hydrostatic pressure difference ΔP between two points separated vertically by a distance h in a liquid of density ρ:
(a) Student P: ΔP=ρgh2
(b) Student Q: ΔP=ρgh
Identify the expression that is dimensionally consistent and give one brief reason for your choice.
