Does anyone know how to compute linepack in a natural gas pipeline? I can't seem to match by hand what is being reported in several simulation programs...thanks for the help!
Although I have used pipe efficiency in the past, I was wondering how it came to be in equations? Was it Panhandle? What does the efficiency really measure?
Thanks for any help...
After conducting a search, I am afraid I could not come up with any answers, so please forgive me if this ends up being a simple question:
Regaring liquid holdup in gas pipelines, the liquid falls out and just sits in the pipeline, not moving...right?
If so, what about calculated holdup...
Folks, I am working on a natural gas pipeline, which will experience liquid holdup. I am concerned that some of this liquid will travel down the pipe into a valley and eventually block the pipeline, preventing the gas from flowing...
How do I determine if this is a legitimate concern?
If I have the composition of a gas, how do I use Pipephase to determine how much propane I can recovery assuming a standard (or typical) cryo plant? What assumptions would I make?
Thanks for the help!

If I have a pipe that will be floated in water, how do I calculate how deep the pipe will sink, or the height at which the water rises along the pipe? Assume the pipe is horizontal and closed at both ends...thanks for the help!
What (or where) are the equations for heat transfer between fluid-pipe-soil?
I have a pipeline simulator and am determining the temperature decline of a gas. The pipeline is buried 3' under the soil line and the soil line is 100' under water. As I run the model with decreasing flow rate, I...
I have a production separator that relieves oil/water/gas to a relief tank. The tank has a relief line (pipe) from the top, extended 25' horizontally away. This relief line vents the gas from the tank. I am trying to calculate the proper size of the relief line.
When the separator exceeds a...

Does anyone know the method of determining the fracture propogation of pipe?
I am trying to determine the resistance to fracture propogation for various grades of pipe. For example, if a pipe fractures under high pressure, what is the propensity for the fracture to continue to adjacent pipes...

How do you calculate the pressure drop in a pipe due to a thermocouple in the middle of the fluid stream?
I have a 4" pipe with water flowing through it and a thermocouple will be permanently inserted into the stream. I see thermocouples can be inserted vertically or at an angle along the...
Can you direct me to some noise calculations regarding fluid flow in small pipes?
Specifically, I have 4" Nominal Pipe. The different fluids I am looking at are Water, CO2, and a production stream comprised of water/oil/gas.
Thanks for the help!
Well, it's been a while sinve I've had to do one of these calculations. Does anyone know what the mass flow rate of CO2 is in lbs/hr if you have 15 MMSCFD flow rate? It's in gaseous form and somewhere near 100-150 F...thanks!
Hey folks! How do I calculate the pressure drop across a valve using a multi-phase fluid?
I am calculating pressure drops through ball valves and check valves, now I need to do the same for 3-way valves. I am at a loss regarding pressure drop for the 3-way valve. Also, after some...
I am modeling a pipeline, which carries an Ethane/Propane Mix. I cannot seem to find any heat capacities or viscosities for a standar mix (80/20).
Can anyone help?
