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

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
