1) C
Combustor or Combustion Chamber is a component in gas turbine , where combustion takes place.
2) A
Gas turbines are in light in weight. so it was used in aircrafts, ships.
3) D
Gas turbine plant operates on Brayton Cycle.
4) C
Power in a gas turbine is produced by gas expansion through rotor only.because in expansion phase , thermal enegy is converted into mechanical energy as the expanding gases turn the turbine rotor.
5) D
Ideal brayton cycle works on isentropic process and isobaric process.
actual brayton cycle works on adiabatic process and isobaric process.
6)A
Fuel is sprayed in combustion chamber and burned converting chemical energy into thermal energy.
