Equal volumes of two immiscible liquids of densities $\rho$  and 2$\rho$  are filled in a vessel as shown in figure. Two small holes are puncherd at depths h/2 and 3 h/2 from the surface of lighter liquid. If ${{\displaystyle v}}_{{\displaystyle 1}}$  and ${{\displaystyle v}}_{{\displaystyle 2}}$  are the velocities of efflux at these two holes, then $v_1$ /$v_2$  is
