Question 1.P.14: Heat is transferred from condensing steam to a vertical surf...
Heat is transferred from condensing steam to a vertical surface and the resistance to heat transfer is attributable to the thermal resistance of the condensate layer on the surface.
What variables are expected to affect the film thickness at a point?
Obtain the relevant dimensionless groups.
For streamline flow it is found that the film thickness is proportional to the one third power of the volumetric flowrate per unit width. Show that the heat transfer coefficient is expected to be inversely proportional to the one third power of viscosity.
