Which type of impeller has highest speed
Backward, Forward ,Straight?
Answer Posted / gurmeet singh
the backward curved has the highest speed.

velocity remains constant, only the relatibe velocity
component changes with the curvation of vane.
In the backward curve vane, it has hightest value of U. (as
per the diagram).
