Swallows migrate from the north to the south every autumn to spend the winter. Ornithologists have discovered that for two-year-old swallows, the relationship between their flying speed $v$ and oxygen consumption $x$ satisfies the function $v=a\log_{2}\frac{x}{10}$. If the oxygen consumption of a two-year-old swallow reaches $40$ units, its flying speed is $v=10m/s$. Then, when the flying speed of a two-year-old swallow reaches $25m/s$, the oxygen consumption reaches \_\_\_\_\_\_ units.
