Air enters the rotor of an axial compressor stage with no pre-whirl $\left(C_{\theta}=0\right)$ and exits the rotor with whirl velocity, $C_{\theta}=150 \mathrm{~m} / \mathrm{s}$. The velocity of rotor vanes, $U$ is $200 \mathrm{~m} / \mathrm{s}$. Assuming $C_{p}=1005 \mathrm{~J} /(\mathrm{kg} \mathrm{K})$, the stagnation temperature rise across the rotor is__________ $\quad \mathrm{K}$ (round off to one decimal place).
