The turbine nozzles function to direct the gases in what direction?

Correct Answer: Option B — In the direction of turbine rotation.

Turbine nozzles are stationary vanes designed to redirect the high-velocity gas stream. By angling the flow in the direction of turbine rotation, they ensure the gases strike the rotor blades at the optimal angle of attack, maximizing the transfer of kinetic energy into mechanical work on the turbine shaft.
