Definition of axial discharge from turbine blades A turbine has axial discharge when the absolute exit steam direction makes what angle with the blade motion (tangential) direction? Choose the correct option.

Q: Definition of axial discharge from turbine blades A turbine has axial discharge when the absolute exit steam direction makes what angle with the blade motion (tangential) direction? Choose the correct option.

Concept Blade motion is tangential; axial discharge means the absolute exit velocity is along the machine axis, which is perpendicular to the tangential direction. Therefore The angle between exit direction and blade motion is 90°. Final Answer 90°

Difficulty: Easy

60°
90°
180°
270°

Correct Answer: 90°

Explanation:

Concept
Blade motion is tangential; axial discharge means the absolute exit velocity is along the machine axis, which is perpendicular to the tangential direction.

Therefore
The angle between exit direction and blade motion is 90°.

Final Answer
90°
