Plotting pressure distribution of fluid flow in a pipe

Click For Summary
SUMMARY

This discussion centers on analyzing the flow of water in a subsea pipe and determining the inner wall temperature of the flowline for accurate temperature distribution plotting. The user has derived an energy equation but seeks clarification on whether the operating temperature of the flowline can be assumed as the inner wall temperature. Additionally, the influence of ambient sea temperature on the inner wall temperature due to convection is highlighted as a critical factor in the analysis.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Knowledge of heat transfer mechanisms, particularly convection

Hi all,

I am analysing the flow of water in a subsea pipe, and have been getting stuck in trying to solve the energy equation to plot a temperature distribution across the pipe diameter

I have derived the equation as such seen in my attachement. But my main question is how should/would I determine the wall temperature of the flowline.

Initially I was assuming to take the operating temperature of the flow line to be the temperature of the inner wall. Am I correct in saying this?
Also there is the ambient sea temperature which could well have an effect on the innerwall temperature due to convection.

What would be the best way for me to determine the inner wall temperature of the flowline?

Assuming operating temp of flowline is:
Assuming ambient sea temp of flowline is:
Steady state

Please see attached my derivation of the energy equation which then results in my final equation I am to use.
