The vessel shown in the figure has two sections of area of cross - section A_(1) and A_(2).A liquid of density rho fills boththe section upto a height h in each . Consider atmospheric pressure P_(0) also . Find (a) the pressure at the base of vessel .(b) the force exerted by the liquid on the base of the vessel . (c ) the downwardforce exerted by the walls of the vessel at the level B |

Answer» Solution :`P_("Bass") = P_(0)+rhog2h` (B) Force applied by the LIQUID on the base ` = (P_(0)+2 rho GH )A_(2)` (c )DOWNWARD force by the walls of the vessel at level `B(N_(b))` = Pressure at `B xx Area ` at the level B . = `(P_(0)+rhogh) (A_(2)-A_(1))` Alternatively `P_(0)A_(1)+N_(B)+(A_(1)H+A_(2)h)rhog = (P_(0)+2rhogh)A_(2)` `N_(B) = P_(0)A_(2) +2rhoghA_(2) - P_(0)A_(t) - A_(1)h_(1)rhog - A_(2) hrhog` ` = (P_(0)+h rho g) (A_(2) - A_(1))`
