Heat Transfer Coefficient of a Pipe Wall

Written by Jerry Ratzlaff on . Posted in Thermodynamics

The resistance to the flow of heat by the pipe wall material can be expressed by the heat transfer coefficient of the pipe wall.

Heat Transfer Coefficient of a Pipe Wall FormulA

\(\large{ p_{wall} =  \frac { 2k }  { d_i  \; \cdot \;   ln  \left(   \frac { p_o }  { P_i  }  \right)   }  }\)         

Where:

\(\large{ h_{wall} }\) = heat transfer coefficient of a wall

\(\large{ ln }\) = natural logarithm

\(\large{ p_i }\) = pipe ID

\(\large{ p_o }\) = pipe OD

\(\large{ k }\) = thermal conductivity
