How to Evaluate Prandtl Number given Recovery Factor for Gases for Laminar Flow?

Prandtl Number given Recovery Factor for Gases for Laminar Flow evaluator uses Prandtl Number = (Recovery Factor^2) to evaluate the Prandtl Number, The Prandtl Number given Recovery Factor for Gases for Laminar Flow formula is defined as the square of recovery factor. In the actual case of a boundary-layer flow problem, the fluid is not brought to rest reversibly because the viscous action is basically an irreversible process in a thermodynamic sense. In addition, not all the free-stream kinetic energy is converted to thermal energy— part is lost as heat, and part is dissipated in the form of viscous work. To take into account the irreversibilities in the boundary-layer flow system, a recovery factor is defined. Prandtl Number is denoted by Pr symbol.
