Hello Kirankumar,

I would recommend you using vista cpd - for you . You just have to specify the  following inputs which is mentioned in the screenshot below , the vista cpd will automatically calculate the power from which you can adjust the torque because power is equal to torque * angular velocity . The angular velocity is radius of rotor *linear velocity. The linear velocity can be calculated from the speed of rotor ie.. pi*dia*N/60 for m/s and N in RPM. So by this way you can give torque as input and create a blade design accordingly so that you achieve the target  power in the results tab . Then use turbogrid for meshing and then use cfx pre and set the boundary conditions and perform a speedline analysis. I am attaching the how to do video link for your reference . Kindly follow this best practice for designing your centrifugal impeller.

I hope this helps you in your simualation.
