if density of air = d
area of crosssection of blades = a
mass of air hitting the blades = avd
v = velocity
K.E. = 1/2 (avd)v^2 = .5 adv^3
So x = 3
Am i right??

From J.R.R. Tolkien's 'The Lord of the Rings':
All that is gold does not glitter
Not all who wander are lost
The old that is strong does not wither,
Deep roots are not reached by frost.
From ashes a fire shall be woken
From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king. |
