The relative velocity of air leaving a straight radial impeller of a centrifugal compressor is $100 \mathrm{~m} / \mathrm{s}$. If the impeller tip speed is $200 \mathrm{~m} / \mathrm{s}$, for a slip free operation, the absolute velocity (in m/s) at the impeller exit is______________(accurate to one decimal place)
