• # question_answer An incompressible liquid flows through a horizontal tube as shown in the adjoining figure. Then the velocity v of the fluid is: A)  3.0 m/s                       B)  1.5 m/sC)  1.0 m/s           D)  2.25 m/s

$AV={{A}_{1}}{{V}_{1}}+{{A}_{2}}{{V}_{2}}$ $\therefore$$A(3)=A(1.5)+1.5Ax({{V}_{2}})$ $\therefore$${{V}_{2}}=1.0\,m/s.$ Hence, the correction option is [c].
