Example calculation

Heat transfer coefficient in pipes

by turbulent pipe flow in smooth pipes

Attention!
This calculation is only a simplified estimation, and does not replace a detailed design calculation.

Input data

  Pipe inside diameter   mm
  Pipe length   mm
  Mass flow   kg/s
  Medium  
  Temperature   °C
  Pressure   bar(a)
 
   
 

Calculation

  Reynolds number    
  Prandtl number    
  Nusselt number    
 

Heat transfer coefficients

  in an infinitely long pipe   W/(m²·K)
  at the pipe inlet   W/(m²·K)
  at the pipe outlet   W/(m²·K)
  mean pipe value   W/(m²·K)
