How to Evaluate Heat Transfer Coefficient given Biot Number?

Heat Transfer Coefficient given Biot Number evaluator uses Heat Transfer Coefficient = (Biot Number*Thermal Conductivity)/Thickness of Wall to evaluate the Heat Transfer Coefficient, The Heat Transfer Coefficient given Biot Number formula is defined as the function of thermal conductivity and thickness of wall. Biot number is the ratio of internal conductive resistance within the body to the external convective resistance at the surface of the body. This number gives the relation between internal resistance and external resistance for heat transfer. This equation is recognized by the name of French physicist Jean Baptiste Biot. Heat Transfer Coefficient is denoted by htransfer symbol.
