A centrifugal air compressor is operating at the following conditions:
Inlet stagnation temperature $=288 \mathrm{~K}$ Inlet stagnation pressure $=1.15$ bar Exit stagnation temperature $=454 \mathrm{~K}$
Exit stagnation pressure $=4.8 \mathrm{bar}$
The energy loss due to non-isentropic compression per unit mass of flowing air (ratio of specific heats, $\gamma=1.4$ and specific heat at constant pressure, $C_{p}=1.005 \mathrm{~kJ} / \mathrm{kgK}$ ) is____________ $\mathrm{kJ} / \mathrm{kg}$.
