How to Evaluate Heat transfer coefficient in film boiling?

Heat transfer coefficient in film boiling evaluator uses Heat Transfer Coefficient by Boiling = Heat Transfer Coefficient by Convection+0.75*Heat Transfer Coefficient by Radiation to evaluate the Heat Transfer Coefficient by Boiling, Heat transfer coefficient in film boiling is a crucial parameter in understanding and analyzing the heat transfer process when a liquid comes into contact with a surface at a temperature significantly higher than its boiling point. In film boiling, a stable vapor layer forms between the liquid and the hot surface, which acts as an insulating layer, reducing the heat transfer rate compared to nucleate boiling. Heat Transfer Coefficient by Boiling is denoted by h symbol.

How to evaluate Heat transfer coefficient in film boiling using this online evaluator? To use this online evaluator for Heat transfer coefficient in film boiling, enter Heat Transfer Coefficient by Convection (h_c) & Heat Transfer Coefficient by Radiation (h_r) and hit the calculate button.
