Oblicz ciśnienie panujące w rowie marjańskim głebokość 11km gęstość wody 1030 ciśnienie atmosferyczne 1000h hPa.
h = 11 km = 11 000 m
d = 1030 kg/m3
pa = 1000 hPa = 100 000 Pa
g = 10 m/s2
szukane:
p = ?
/
p = ph + pa
p = dgh + pa
p = 1030kg/m3 *10m/s2 *11000m + 100000Pa
p = 113300000Pa + 100000Pa
p = 113 400 000 Pa
1 MPa = 1000 000 Pa
p = 113,4 MPa
============
Odp.Szukane ciśnienie wynosi 113,4 MPa (megapaskala)
