Exercices statique des fluides

1) P= P atm + alcool x g x h
P = 105+ 0,8 x1000 x 10 x 0,13 = 105+1040 = 101040 Pa
2) P effective = alcool x g x h = 1040 Pa
Correction

Pression due à l’eau = pression hydrostatique = mer x g x h
P hydro = 1030 x 10 x 11022 = 113526600 Pa = 1135,266 x 105Pa = 1135,266 bar
