Hello everyone,

 

I am performing TSV sizing calculation to protect a 14'' pipeline.

 

Handling fluid is crude oil.

 

Solar radiation is 82 degC.

 

Anyone pls reply here, how to calculate Isothermal Compressibility Coefficient (χ)?

 

Regards,

Peru.

Perumal, 

 

you can calculate the pressure rise due solar radiation using simulation software as per following steps: 

 

1- Creat stream of the crude oil under normal temp and pressure.

2- Copy same stream using solar radiation temperature.

3- Adjust the pressure of the new stream till you get same density of the original stream.
