Oblicz cisnienie panujace na dnie jeziora o glebokosci 100 metrow gestosc wody wynosi 1000kg/m3 cisnienie atmosferyczne okolo 1000hpa

p=d*g*h p=1000kg/m3*10*100m= 1000000hPa = 2Pa

dane h=100m, d=1000kg/m3, po=1000hPa, g=10m/s2=10N/kg szukane p p = po + ph........ciśnienie hydrostatyczne ph = dgh p = po + dgh = 1000hPa + 1000kg/m3*10N/kg*100m = 1000hPa + 10 000hPa = p = 11 000hPa 2/ dane h=30m, d=1000kg/m3, po=1000hPa, g=10m/s2=10N/kg, szukane p p > dgh = 1000kg/m3*10N/kg*30m = 300 000 Pa = 3000 hPa p > 3000 hPa
