centrifugal fan

hi i am solving the centrifugal fan in the cfx11.0. i am getting less pressure drop at inlet and outlet from simulation in comparasion of the experiments. i used the K_epsilon, K- omega and sst K-omega but in all the cases it is more or less same. i gave the velocity inlet and the pressure out let condition.
why it is happening so? Any suggestions you are welcome.

Check your mesh, convergence, and time step sensitivity. Check your physics are correct. Check the experiment is correct too.
