Flow through fixed (stator) blades in a reaction turbine When steam flows through the fixed blades (nozzle passages) of a reaction turbine, how do pressure and velocity change? Choose the correct option.

Difficulty: Easy

Pressure increases while velocity decreases
Pressure decreases while velocity increases
Pressure and velocity both decrease
Pressure and velocity both increase

Correct Answer: Pressure decreases while velocity increases

Explanation:

ConceptIn a reaction turbine, the fixed blades act as nozzles. Across a nozzle, steam expands: pressure drops and kinetic energy (hence velocity) rises.

ThereforePressure ↓, Velocity ↑

Final AnswerPressure decreases while velocity increases
