h_∞ = h₀-(V_∞^2)/2
This formula uses 3 Variables

Variables Used

Freestream Specific Enthalpy - (Measured in Joule per Kilogram) - Freestream specific enthalpy is the enthalpy of the continuous flow of fluid and the sum of the internal energy E plus the product of the pressure p and volume V.
Total Specific Enthalpy - (Measured in Joule per Kilogram) - Total Specific Enthalpy defined to be the sum of the internal energy E plus the product of the pressure p and volume V.
Freestream Velocity - (Measured in Meter per Second) - The Freestream Velocity is the velocity of air far upstream of an aerodynamic body, that is before the body has a chance to deflect, slow down or compress the air.

STEP 1: Convert Input(s) to Base Unit

Total Specific Enthalpy: 200 Joule per Kilogram --> 200 Joule per Kilogram No Conversion Required
Freestream Velocity: 100 Meter per Second --> 100 Meter per Second No Conversion Required
