A centrifugal compressor requires $1800 \mathrm{~kW}$ of power to compress $10 \mathrm{~kg} / \mathrm{s}$ of air. Consider the whirl velocity component is equal to the impeller speed (ie., no slip) and no losses in the impeller. If the impeller has to rotate at $1900 \mathrm{rad} / \mathrm{s}$, the diameter of the impeller is to be________________ $\quad \mathrm{m}$ (in two decimal place).
