Gents,
I am facing a turbine which has a 130 inches exhaust to condenser.
would you please let me know why caesars nema sm23's modulus doesn't cover it?

We need more information, can you send your NEMA data file in to Tech Support?

It is a mitsubishi's made horizontal steam turbine;
There are three nozzles;
first one 10" main stop valve,
2nd one 14" induction inlet
and 3rd one 11'-1.86" exhaust outlet to the condenser
actually we can calculate Nema's formula by hand or by using Excell but I am wondering why caesar has a limitation of 88" ?

No, not that. I want your actual data file so we can run here, without typing in any data. We need the file with the .NEM suffix so we can run with "your" data, exactly as you typed it in.

Ok, I grabbed your file, renamed it, and ran it. I had no issues running this file. Here is the ouput.

What version and build are you running?

I thought you are going to run it with real exhaust size which is 11'-1.86",...

It looks to me like this module was setup with a maximum nozzle nominal diameter of 88 inches. I don't know why that was done. At the moment that is as big as you can go.

We'll check into this and hopefully we can make some sort of adjustment here for the next version of the software.
