Modeling a Gas Pipe using Aspen Hysys V11

[@tringuyen1979]

Hi Collins, how can we find the flowrate of a existing pipeline with known parameters like pressure difference, temperature,... by using Aspen Hysys 11?

[@collinsmordi8721]

No you need the flowrate inorder for you to be able to size the pipeline

[@tringuyen1979]

@@collinsmordi8721thanks for your reply. The problem is that I dont need to size the pipe, because I already had it. Lets say we have a steam header, from the header we have a 4" branch with some fittings to the process. How can we find the flow rate of steam that can be supplied to the process via that branch by using Hysys? Just want to compare with my manual calculation.

[@collinsmordi8721]

The header is originally designed to handle a particular flowrate and those branches are designed to carry a certain ratio of the total flow the header is designed to carry, a tee in Hysys can be used to model the branches of the header based on desired stream ratios from the header

Hi sir, what should i put in my pipe segment if i have reducer and stub in fittings? and when do i use swage abrupt? any videos regarding this for me to watch?

[@ankushnikam2950]

Thank you for this explanation. How we can calculate htc , is it mandatory to provide this input to simulate gas pipeline as this input is not require for liquid pipeline

[@collinsmordi8721]

The overall htc can be calculated using h=q/∆t where q is the heat flux. To simulate gas pipeline it is required
