Hello,
I try to shape a vacuum pump with a compressor and a heat exchanger afterwards.
First of all I compress a simple nitrogen stream with a pressure of 0.01 bar to 1 bar. With an inlet temperature of 25°C and an massflow of 40,7 kg/h I receive an input power of 190499201654756000000,0 kW. The increase of temperatur is physically correct. What`s my problem?
Thanks
Michael
