WebFor turbulent flow there is no simple analytic treatment, but there is an empirical equation called the Darcy–Weisbach equation: P − P 0 = f D l 2 r ρ V 2 2 where V is the flow velocity and f D is an empirically measured constant called the Darcy friction factor. There is an online calculator for the Darcy-Weisback equation here. Share Cite WebDec 28, 2024 · The pressure ( P ) at any depth ( d ) is given by the equation: P = ρgd P = ρgd. Where ρ (“rho”) is the density of the liquid and g is the acceleration due to gravity (on Earth, g = 9.81 m/s 2 ). The density of water at 20 °C is ρ = 998 kg/m 3, but generally the calculations are greatly simplified if you assume a temperature of 4 °C ...
