A turbine is said to have an axial discharge when the steam leaves the blade tip at __________ to the direction of the blade motion.

[A]. 60°
[B]. 90°
[C]. 180°
[D]. 270°

The answer should be 90°. If we see velocity diagram for axial discharge, then its clear that it make 90° with the blade tip.

Dear @Vinit, how can you prove that is 90 degree?

Please discuss.

Here velocity is axially discharging so answer is 90.

Pradnya Dhainje said: (Jan 4, 2015)  
Velocity diagram for axial discharge, it should be clearly mention that is 90.

When the flow of steam is parallel to turbine blade than it is known as radial flow turbine, but when flow flowing through perpendicular to the shaft (90 degree) than it is known as axial flow turbine.

I feel there are stator blades between each stage of the turbine which convert the steam flow from radial to axial flow otherwise if you view it nature then the flow is parallel to the turbine blade which is radial flow only.

And it is parallel to turbine axis.

Sandeep said: (Feb 11, 2017)  
Yes, you are right @Kalpesh.

60° only.

Siddu said: (Sep 17, 2017)  
No, 60 degree is the correct answer.

M S Nayak said: (Nov 17, 2017)  
answer is A.

In case of axial flow it is parallel to the axis i.e less then 90.
In case of radial flow perpendicular to the axis i.e 90.

Correct Answer is 60°.

Mayank said: (Jul 26, 2018)  
Because it is perpendicular to the blade.
