C_D = E/(0.5*ρ_∞*V_∞^2*d)
This formula uses 5 Variables

Variables Used

Drag Coefficient - Drag Coefficient is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
Energy for Blast Wave - (Measured in Joule) - Energy for Blast Wave is the amount of work done.
Freestream Density - (Measured in Kilogram per Cubic Meter) - Freestream Density is the mass per unit volume of air far upstream of an aerodynamic body at a given altitude.
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.
Diameter - (Measured in Meter) - Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.

STEP 1: Convert Input(s) to Base Unit

Energy for Blast Wave: 1200 Kilojoule --> 1200000 Joule (Check conversion here)
Freestream Density: 412.2 Kilogram per Cubic Meter --> 412.2 Kilogram per Cubic Meter No Conversion Required
Freestream Velocity: 102 Meter per Second --> 102 Meter per Second No Conversion Required
Diameter: 2.425 Meter --> 2.425 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_D = E/(0.5*ρ_∞*V_∞^2*d) --> 1200000/(0.5*412.2*102^2*2.425)

Evaluating ... ...

C_D = 0.230776279653173

STEP 3: Convert Result to Output's Unit

0.230776279653173 --> No Conversion Required

FINAL ANSWER

0.230776279653173 ≈ 0.230776 <-- Drag Coefficient
