Latent Heat Transfer Rate in a Pipeline help please

AI Thread Summary
The discussion revolves around determining the rate at which liquids condense from a gas pipeline, with the user utilizing a chemical process modeling program. They have access to various parameters, including heat of vaporization and fluid enthalpy changes, but are uncertain about incorporating kinetic and potential energy changes into their energy balance calculations. The user seeks clarification on how to effectively set up their energy balances, particularly distinguishing between total heat transfer and latent heat transfer. They request a specific problem to focus on for better understanding. The inquiry highlights the complexities of modeling latent heat transfer in dynamic systems.

Hey guys, first post.

I'm trying to determine to the rate at which liquids drop out of a gas pipeline. I've modeled the system in a chemical process program, but its only a steady state model. Anyways, here's some of what I can get out of that program:

Heat of vaporization
Total Heat Transfer
Kinetic Energy Change
Potential Energy Change
Fluid Enthalpy Change

and all the fluid properties you can imagine.

I know about latent heat transfer and how to set it up the standard evaporation cooling scenario, where you have your energy balance for the air and one for the water. But in this case where potential and kinetic are changing as well, I'm not sure how to set up my energy balance(s). Don't want all "Total Heat Transfer" encompasses... I'm told that that includes any latent heat transfer and heat transfer between the pipe and its surroundings but I'm not sure. And don't get me started on Fluid Enthalpy change...

Please help.

Can you please provide a specific problem to focus on?
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
