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 [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
5.6 Questions Collins, p.107 [cid:image002.jpg@01CC94C6.C4A53AA0] Notes: ρfresh water = 1,000kg/m3 g = 10N/kg 1,000mbar = 1 bar = 100,000Pa 5.6 Plenary · Which diver experiences the greatest pressure? [cid:image003.jpg@01CC94C6.C4A53AA0]
