Hej all,

Is this the right forum to post a question on sonic nozzle calculations?
If not please bear over with me.

The problem is to design a sonic nozzle giving a fixed flow at fixed input conditions: 1,2MPa, atmospheric air, 20.. 21deg Celcius, free to atmosphere at exhaust side of nozzle.
I need a flow of approx. 0,93 kg/s. If anyone have don this please show me the way.

Rimfaxe, newbee
