I faced a problem during the application of API 581-2016 edition and I hope you could help me in this issue.
I am trying to apply RBI for a steam vessel , when I chose the representative fluid as steam , no release rate was calculated , this is because of the huge value of Cp that was calaculated for steam refer to note 3 in table 4.2 in API 581 -2016 , when using this huge value to calculate k k=Cp/(Cp-R) ,where R=8.314 the result equal to 1.
If you use k=1 in gas release rate equation (equation 3.6 or 3.7- API 581-2016) there will be no result so there will be no consequence . , temperature used is 773 K
