Oblicz ciśnienie wywierane na dno naczynia w którym do wysokości 30 cm wlano
a) oliwe
b) nafte
c) wode
p = ρgh
h = 30 cm = 0,3
a)
ρo = 920 kg/m³
po = ρo*g*h = 920 * 10 * 0,3 = 2760 Pa
b)
ρn = 810 kg/m³
pn = ρn*g*h = 810 * 10 * 0,3 = 2430 Pa
c)
ρw = 1000 kg/m³
pw = ρw*g*h = 1000 * 10 * 0,3 = 3000 Pa
