Gas Turbine Quiz

Which of the following is the main working fluid in a gas turbine?

• Water

• Steam

• Air

• Mercury

The Brayton cycle is also known as:

• Otto cycle

• Diesel cycle

• Joule cycle

• Rankine cycle

In a simple open-cycle gas turbine, the air is compressed:

• Isothermally

• Adiabatically

• Isochorically

• Isobarically

The main components of a basic gas turbine are:

• Compressor, Combustor, Turbine

• Boiler, Turbine, Condenser

• Pump, Combustor, Turbine

• Compressor, Pump, Condenser

The function of the compressor in a gas turbine is to:

• Increase the velocity of air

• Increase the pressure of air

• Increase the temperature of air

• Decrease the pressure of air

The exhaust gases from a gas turbine are generally:

• At atmospheric pressure

• At high pressure

• At low temperature

• At high temperature

The efficiency of a gas turbine increases with:

• Decreasing the pressure ratio

• Increasing the pressure ratio

• Decreasing the temperature

• Increasing the fuel flow

The power output of a gas turbine can be increased by:

• Reducing inlet air temperature

• Increasing exhaust temperature

• Increasing compressor work

• Reducing fuel input

In a gas turbine, the combustor is used to:

• Compress air

• Burn fuel and heat air

• Cool the exhaust

• Increase the pressure of exhaust gases

Which of the following is NOT a type of gas turbine?

• Turbojet

• Turboprop

• Turboshaft

• Reciprocating
