HT 9.4 Heat Transfer in Laminar Pipe Flow
Channel: Sunthar's Lectures in Chemical Engineering
Date: 2021-03-17

Summary:
* In fully developed flow Nu is constant 
  - equal to 4.36 (for constant surface flux condition)
  - equal to 3.66 (for constant surface temperature condition)
* Entry length effects leads to a larger Nusselt number due to 
  - smaller (developing) boundary layer near the entrance or
  - higher Peclet number
