Peclet Number
Peclet number is proportional to { (bulk heat transfer) / (conductive heat transfer) } and is used in heat transfer in general and forced convection calculations in particular. It is equivalent to (Re.Pr). It is normally defined in one of the following forms :

Formula 1: Pe = (D * V * ρ * Cp) / k
Formula 2: Pe = (D * G * Cp) / k
Formula 3: Pe = (D * V) / α
| alpha | = | Thermal diffusivity |
| Cp | = | Heat capacity |
| D | = | Characteristic length |
| G | = | Mass velocity |
| k | = | Thermal Conductivity |
| rho | = | Density |
| V | = | Velocity |
