Hi everyone

 

I am sizing a PSV for two phase flow and i have to perform it according to the method Direct Integration of the Isentropic Nozzle Flow wich it is mentioned in API 520 Apendix C.2.1,

My answer is if everyone knows how to calculate the density for every pressure mentioned in table C.2 of API 520.

 

it would be very helpful 

 

Thanks

The calculation is best performed with the aid of a process simulator to calculate  mixture properties as a function of pressure. It is very difficult without this. Prode Properties offers a free database and Excel calculation for just such endeavor.
