Consider two identical tanks with a bottom hole of diameter $d$. One tank is filled with water and the other tank is filled with engine oil. The height of the fluid column $h$ is same in both the cases. The fluid exit velocity in the two tanks are $V_{1}$ and $V_{2}$. Neglecting all losses, which one of the following options is correct?

 

  1. $V_{2}>V_{1}$
  2. $V_{2}=V_{1}$
  3. $V_{2}<V_1$
  4. Insufficient data to definitively conclude the relationship between $V_1$ and $V_2$
