Dane:
ρ = 998 kg/m³
g ≈ 10 m/s²
a) h = 10 m
Szukane:
p = ?
p = ρgh
p = 998 kg/m³ * 10 m/s² * 10 m = 99 800 Pa = 998 hPa [kg/m³ * m/s² * m] = [Pa]
Odp.: 99 888 Pa.
b) h = 1 km = 1 000 m
p = ρgh
p = 998 kg/m³ * 10 m/s² * 1 000 m = 9 980 000 Pa = 9 800 hPa [kg/m³ * m/s² * m] = [Pa]
c) h = 10,911 km = 10 911 m
p = ρgh
p = 998 * 10 m/s² * 10 911 m = 108 891 780 Pa = 1 088 917,8 [kg/m³ * m/s² * m] = [Pa]hPa
