A centrifugal pump rotates at $N = 1450\text{ rpm}$ and delivers $Q = 0.04\text{ m}^3\text{/s}$ at a total head of $H = 16.0\text{ m}$. The specific speed $N_s = \frac{N \sqrt{Q}}{H^{3/4}}$ in metric units (with $N$ in rpm, $Q$ in $\text{m}^3\text{/s}$, $H$ in meters) is ________ (round off to 1 decimal place).
