The flooding velocity curves for two different structured packings are shown in the figure. The ratio of mass velocities of liquid $\left(G_{x}\right)$ to that of the gas $\left(G_{y}\right)$ is $1.27$. The density of the liquid ( $\rho_{x}$ ) is $1200 \mathrm{~kg} \mathrm{~m}^{-3}$ and that of the gas ( $\rho_{y}$ ) is $1.2 \mathrm{~kg} \mathrm{~m}^{-3}$. For both the packings, the allowable superficial vapor velocity is $60 \%$ of flooding velocity ( $u_{0, F}$ ). The ratio of allowable mass velocity of the vapor in packing P to that in packing Q is $\_\_\_\_$ (rounded off to one decimal place).
