The Eckert Number (Ec) is a crucial dimensionless quantity in fluid dynamics and heat transfer. It represents the ratio of a fluid's kinetic energy to its specific enthalpy difference, indicating the importance of viscous dissipation relative to heat convection. Use our free Eckert Number calculator to accurately determine this parameter for your engineering and physics applications.
Formula:
The Eckert Number (Ec) is calculated using the following formula:
Ec = U2 / (cp * ΔT)
Where:
- U = Characteristic flow velocity (m/s)
- cp = Specific heat at constant pressure (J/kg·K)
- ΔT = Characteristic temperature difference (K or °C)
