i need the formulas for designing centrifugal compressor of single stage which helps to compress the refrigerant

the refrigerant needs a pressure differance of 1.3bar..single stage...we don hav any ideas about the material to used..the motor we use to run compressor is 100 watts..the speed can b more than 1500 rpm..we had a initial calculation far diameter of the impeller blade..but struck up with the no. of blades..we are terribly confused..so suggest us the procedures to proceed with our requireement..

This is not really a project that you can expect to design unless you have the education and experience behind you.

Try here.

Or here.

100 watts is just over 1/10 HP so it's going to have to be a very small turbine.

"we don hav any ideas about the material to used"
Do you mean the refridgerant?

It's no good asking a question like this unless you know your gas and the rest of the system and how much heat it needs to move.
