why torque is half than expected?

I need to calculate power coeff. so I ask FLUENT to print me moment. I use this moment to calculate power coeff. in this way;
P=T*W where T:torque (moment that I can get from FLUENT), W:rot. speed [rad/s]
CP=p/(1/2*rho*A*U^3) where rho:density, A:area, U:freestream vel
But the CP that I calculate in this way is the half of the CP that I calculate analytically...
If someone knows sth about this I will be glad.
