| Which of the following statements represents the function the nozzle assembly performs in an impulse turbine? |
| A) Converts the steam's thermal energy into kinetic energy by increasing its velocity and directing it against the rotor blades. |
| B) Provides an area where the steam is prevented from expanding prior to being directed against the rotor blades. |
| C) Increases the velocity of the steam without a pressure drop across the diaphragm. |
| D) Converts the potential energy of steam into thermal energy by increasing its pressure and directing it against the turbine blades. |
