Hi friends,
I am a new member in this group.
I request everybody to accept me as a member of this group.
I am having some probs.
- How to calculate the following things for given volumetric flow of gas:
- Pipe dia.
- Pipe thickness/ pipe schedule no.
- Pressure drop/kilometer of pipe length.
- For most economical transmission of gas through pipe at what pressure the
gas is to be transmitted?
On what factors it depends, please elucidate.
- What is the maximum gas velocity allowed in the pipe?
- What are limiting factors for deciding the above things?
- How to calculate the compressor power required for boosting the pressure
of the gas?
- Due to flow of gas through pipe there may be increase in temperature of
the gas; how to calculate the temperature rise due to friction?
Does it have any safety related aspects?
If yes then how to counteract this?
7. What is the value of the natural gas viscosity?
8. I have tried two formulas
- Waymouth &
- Fanning's formula
Even though both are applicable for the gas flow through pipe but the
pressure drop calculated by these formulas gives different values.
Please clarify.
For e.g. Volume flow = 40 mmscmd
Inlet pressure = 10 bar
Inlet temperature = 30 oC
Pipe length = 500 km
Your answers are highly appreciated
Regards
Sudhir
