engineering recuitment UPPSC AE Mock Test 2024 Power Engineering Air and Gas Compressors Axial Flow Compressors
For axial flow compressor, the reaction ratio in terms of rotor blade angle at inlet (β1), at outlet (β2) and flow coefficient (θ) is
1
2ϕ (tan β1 - tan β2)
2
2ϕ (tan β1 + tan β2)
3
\(\frac{\phi}{2}(tan\beta _1 ~-~tan\beta_2)\)
4
\(\frac{\phi}{2}(tan\beta _1 ~+~tan\beta_2)\)
