1. The problem statement, all variables and given/known data Prove that P1>Po 2. Relevant equations dp=-rho(g)dy integral(Po,P1)dp=-integral(Y2,Y1) rho(g)dy 3. The attempt at a solution dp=-rho(g)dy intgrl(Po,P1) dp=-integral(Y2,Y1) rho(g)dy Po-P1=-(rho(g))(Y2-Y1) Po-P1=(rho(g))(Y1-Y2) Y2-Y1-->Y1-Y2<0 defined as -del(y) Po-P1=-(rho)(g)(del(y)) P1-Po=+(rho)(g)(del(y)) not sure where to proceed or if this proves that P1>Po. Please help. Oh and the attached file has a diagram on it.
