Hello Everyone,

 

I would like to know the answer to the following question, presented in abstract form:

 

A hot fluid (from example, 200 degrees celsius) enters a pipe system say 1000 meters long. How can I find the temperature of the fluid when it exits the pipe. I have all other information, in terms of the insulation used, pipe thickness, ambient temperature, etc.

 

I would simply like to know the methodology and equations I need to give me a rough estimate of the temperature drop the fluid will experience. I mainly want to consider the heat loss through conduction as this will be the greatest contributor.

 

Your assistance will be much appreciated.

 

Regards,

Kush

Kush,

 

Refer the link below for an excel spreadsheet for pipe heat loss:

Thanks Mr Srivastava,

 

Will look into it. My main issue is that I am designing a molten sulphur line between two sulphur pits. These points are 700 meters apart. I have already taken a look some of your other forums with regards to this and how to calculate the amount of steam required for the steam jacket.

 

However I wanted to know if it is possible to simply supply steam at the start of the pipeline rather than at mutiple points. The Sulphuric Acid Manufacture Handbook advises that you supply fresh steam every 12 meters, however this will greater increase the cost and setup time of the project. I will need to installed a seperate steam pipeline/header which will have to run along the main jacketed sulfur line.

 

On a side note we currently have a similar installation, however this is only 200 meters long and steam is supplied only at one point at the start of the line. So far we have not faced any problems in terms of sulfur solidification and it seems to be running well.

 

Your experience guidance on this matter will be much appreciated.

Kush
