How to Calculate Outlet Pressure and Temperature in a Pipe?

Click For Summary
SUMMARY

The discussion focuses on calculating outlet pressure and temperature in a pipe with specific parameters: an outer diameter of 25mm, inner diameter of 24mm, length of 84mm, normal inlet pressure of 6 bar, normal inlet temperature of 150°C, maximum inlet pressure of 11.5 bar, maximum inlet temperature of 230°C, and a mass flow rate of 4 kg/min. To determine the outlet conditions, users should calculate the Reynolds number, friction factor, head loss, and pressure drop, assuming a roughness factor of 0.00015 ft for the piping. The analysis must consider turbulent flow and friction unless ideal conditions are explicitly stated.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Knowledge of Reynolds number calculation
  • Familiarity with friction factor determination in turbulent flow
  • Basic concepts of head loss in piping systems
NEXT STEPS
  • Research how to calculate the Reynolds number for fluid flow
  • Learn about the Darcy-Weisbach equation for head loss
  • Study methods for determining friction factors in turbulent flow
  • Explore the impact of pipe roughness on flow characteristics
USEFUL FOR

Engineers, fluid mechanics students, and professionals involved in piping system design and analysis will benefit from this discussion.

Outer dia=25mm,Inner Dia=24mm,Length=84,Normal innlet pressure=6 bar,Normal inlet temp=150°C,Max innlet pressure=11.5 bar,Max innlet temp=230°C ,Mass flow rate=4 kg/min,
what is the Outlet pressure&Temp?.Which formula I have to Use.Pls Help me

Are you given any equations, the viscosity, or the piping material?

To solve this I would assume a roughness factor for the piping (e=0.00015 ft is good) and calculate the reynolds number, then the fraction factor, then head loss, and then finally a pressure drop.

Unless the problem specifically tells you to assume ideal conditions and zero friction, you have to assume it is turbulent flow and use a the friction factor - otherwise the scenario is bogus!

Please let me know if you have any more info and we will solve this.
