While designing blades, the blade angles are defined using the flow
triangles, these again are based on the rotational speed and the flow rate
at which the blade is designed for.

Hence I cannot directly say what will be the theta and beta for this case.

As for the training I had sent an email with regards to this early last week
I am not sure why you did not receive it.

Anyways we are planning for the training on 26th and 27th of December

26th - Turbomachinery training
27th - multiphase training

Please let me know if you have any queries on this.
