Power required for given total drag force Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
