Best ResponseYou've already chosen the best response.0Hi you can use Bernloli equation between two point A & B dw:1332158745342:dw \[P _{0}+(1/2)\rho v^2=P _{0}+\rho gy\]we now that velocity in top of water is negligible

Best ResponseYou've already chosen the best response.0dw:1332170757662:dw apply conservation of energy theorem: total mechanical energy at the top=total mechanical energy at the base Po(pressure energy)+0(kinetic energy)+\[\rho\]gh(potential energy)=Po(pressure energy)+1/2\[\rho\]V^2(kinetic energy)+0(potential energy)..... put the value in the above equation and get the value of V.
