So, now, this theory and the previous theory are compactable. Do you understand? Yeah.
So, also we can write now tan beta I is equal to tan beta 1 plus A divided by on minus A
dash. This, this, is the derivation we can get from the blade element theory. We can
calculate the efficiency of an element. Now, if we assume that all the elements of the
blade produce the same efficiency that this will be the efficiency of the overall propeller.
