The correct answer is: (a) $h_3 = h_1$

Work Step by Step

The continuity equation is: $A_1~v_1 = A_2~v_2$ By the continuity equation, we know that the flow velocity is the same at $A_1$ and $A_3$ since $A_1 = A_3$. Therefore, the pressure is the same at $A_1$ and $A_3$. Since the pressure is the same, then $h_3 = h_1$. The correct answer is: (a) $h_3 = h_1$
