| What are the two principle functions of the turbine nozzle guide vanes? |
| A) Convert the heat energy of the hot gases into kinetic energy and direct the flow of gases to the turbine rotor blades. |
| B) Convert the potential energy of the hot gases into heat energy and direct the flow of gases to the turbine rotor blades. |
| C) Convert the heat energy of the hot gases into potential energy and direct the flow of gases to the compressor rotor blades. |
| D) Convert the heat energy of the hot gases into potential energy and direct the flow of gases to the turbine rotor blades. |
