The pressure on the two sides of the impulse wheel of a steam turbine_____?
Correct answer: A. is same
- A. is same
- B. is different
- C. increases from one side to the other side
- D. decreases from one side to the other side
Explanation
In an impulse wheel, the moving blades only change the velocity and direction of steam; ideally, they produce no pressure drop. Therefore, the pressure on both sides of the wheel is approximately the same.
