Ec = Eckert number

V = speed

Cp = specific heat

DT = temperature difference

The Eckert number is a dimensionless number used for flow calculations. It was named after Professor Ernst R. G. Eckert.

It provides a relationship between flowing kinetic energy and enthalpy and is used to characterize dissipation.

The above equation can also be defined as Exeter number = kinetic energy/enthalpy.

Usage example

Input data:

Speed (V): 25 m / s

Specific heat (cp): 15 joules / kg - Kelvin

Temperature difference (DT): 20 absolute temperature (Kelvin)

Click "Calculate" to output data

Eckert number (Ec): 2.0833
