How to Evaluate Wetted Perimeter given Reynolds Number of Film?

Wetted Perimeter given Reynolds Number of Film evaluator uses Wetted Perimeter = (4*Mass Flow of Condensate)/(Reynolds Number of Film*Viscosity of Fluid) to evaluate the Wetted Perimeter, The Wetted Perimeter given Reynolds Number of Film formula is defined as the function of mass flow rate of condensate, Reynolds number of film, viscosity of fluid. In filmwise condensation a laminar film of vapor is created upon a surface. This film can then flow downwards, increasing in thickness as additional vapor is picked up along the way . In dropwise condensation vapor droplets form at an acute angle to a surface. Wetted Perimeter is denoted by P symbol.
