5.6 recall and use the relationship for pressure difference: pressure difference = height × density × g ∆p = h × ρ × g ∆p = pressure of the fluid (N/m2 or Pa) h = height of the fluid (m) ρ = density of the fluid (kg/m3) g = gravitational field strength (N/kg) 5.6 Demo - squirting water column 12 October 2011 07:24 [cid:image001.jpg@01CC94C6.C4A53AA0] · The bottom hole squirts water the furthest
· Because the water at the bottom has the greatest pressure
· Because in the formula ∆p = h × ρ × g, ρ is constant, g is constant and h is large
· So ∆p = large
