I am doing analysis of turbine in Fluent. I got the force applied on the blades by the fluid in the result< report< force.

I am interested to know the rotational velocity of turbine in rad./sec or rpm. 

please help me to get a way to know rotational velocity.

You'll need to calculate this: ie the axial force will suffer friction losses from the gearbox/generator and then turn the blades at a certain speed. The solver either need the speed to rotate or a function of force related to speed. We can't calculate the speed purely from a force.
