Water is to be condensed at 1 atmosphere pressure in a compact heat exchanger having vertical stainless steel plates at 40ºC. Plot the condensation boundary layer thickness flowing down the vertical surface as a function of the distance down the plate, assuming laminar flow. At what point would you assume the condensate flow to become turbulent?

What will be an ideal response?


Assuming laminar flow of condensate down a vertical surface, Equation 10-34 may be

used to predict the condensate thickness.
