127) The degree of reaction of an axial flow turbine is the ratio of isentropic temperature drop in a blade row to the

adiabatic temperature drop in the stage

total temperature drop

total temperature drop in the stage

total adiabaitc temperature drop

Answer is:

total temperature drop in the stage

isothermal

isentropic

adiabatic

isochoric

Answer is:

gas turbine uses low air-fuel ratio to economise on fuel

gas turhine uses high air-fuel ratio to reduce outgoing temperature

gas turbine uses low air-fuel ratio to develop the high thrust required

all of the above

Answer is:

increase in net output but decrease in thermal efficiency

increase in thermal efficiency but decrease in net output

increase in both thermal efficiency and net output

decrease in both thermal efficiency and net output

Answer is:
