P(N/m**2)=F(N)/S(m**2)
N/m**2=Pascal
1bar = 10**5 Pa
Patm(20degre)=1013mbars

Pb-Pa = pliq*g*(Za-Zb)
Pabs = Prelative+Patm 

-----------------------

Ex 01: Cric hydraulique
P=F/S
Pa= 150/pi*0,005**2
Pa=Pb car meme altitude

Pb=F/S -> Fb=P*S

Ex 02: Resevoir deux tubes 
Pa=Patm=1013mbars

1)Pb-Pa=p*g*h
  Pb=Pa+p1*g*h1 
2)Pa-Pe=p1*g*(Ze-Za)
Ze=Za
Pb-Pe=p1*g*(Ze-Zb)
Pb-Pe/p1*g=Ze-Zb
Ze= Pb-Pb/p1*g    +Zb
=... 
3)Pc-Pb=p2*g*(Zb-Zc)
Pc=Pb+p2*g*(Zb-Zc)
4)Pc-Pd=p1*g*(Zd-Zc)

Ex 03: Tube bouche 
P1=P3=Patm=1,013*10**5  
P2-P1=pliq*g*(Z1-Z2)
1bar=10**5 Pa

Ex 04: P2-P3= phg*g*(Z3-Z2)
Z2=Z3
P2-P3=0 
P2=P3
pal*g*h1=peau*g*h2

pal=peau * h2/h1 

Ex 05: 
P1-P0= peau*g*(ZO-Z1)
       
P1-P2= pliq*g*(Z2-Z1)
P3-P1+P1-P2-P3 = 0
