132) Pick up the wrong statement

large gas turbines employ axial flow compressors

axial flow compressors are more stable than centrifugal type compressors but not as efficient

axial flow compressors have high capacity and efficiency

axial flow compressors have instability region of operation

Answer is:

axial flow compressors are more stable than centrifugal type compressors but not as efficient

less

same

may be less or more depending on ambient conditons

Answer is:

large gas turbines use radial inflow turbines

gas turbines have their blades similar to steam turbine

gas .turbine′s blade will appear as impulse section at the hub and as a reaction section at tip

gas turbines use both air and liquid cooling

Answer is:

high pressure ratio

increasing gas temperature

high specific volume

paucity of 02.

Answer is:

gas turbine requires lot of cooling water

gas turbine is capable of rapid start up and loading

gas turbines have flat efficiency at part loads

gas turbines have high standby losses and require lot of maintenance

Answer is:
