Freestream Velocity given Total Drag Force Solution

STEP 0: Pre-Calculation Summary

Formula Used

Freestream Velocity = Power/Drag Force
V_∞ = P/F_D
This formula uses 3 Variables

Variables Used

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.
Power - (Measured in Watt) - Power is defined as the product of thrust force and velocity of aircraft.
Drag Force - (Measured in Newton) - Drag Force is the resisting force experienced by an object moving through a fluid.

STEP 1: Convert Input(s) to Base Unit

Power: 3000 Watt --> 3000 Watt No Conversion Required
Drag Force: 99.99 Newton --> 99.99 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_∞ = P/F_D --> 3000/99.99

Evaluating ... ...

V_∞ = 30.00300030003

STEP 3: Convert Result to Output's Unit

30.00300030003 Meter per Second --> No Conversion Required

FINAL ANSWER

30.00300030003 ≈ 30.003 Meter per Second <-- Freestream Velocity

(Calculation completed in 00.022 seconds)
