Lift Per Unit Span by Kutta-Joukowski Theorem Solution

STEP 0: Pre-Calculation Summary

Formula Used

Lift per Unit Span = Freestream Density*Freestream Velocity*Vortex Strength
L' = ρ_∞*V_∞*Γ
This formula uses 4 Variables

Variables Used

Lift per Unit Span - (Measured in Newton per Meter) - Lift per Unit Span is defined for a two-dimensional body. The lift is the component of resultant force (caused by pressure and shear stress distribution) perpendicular to the freestream velocity.
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 signifies the speed or velocity of a fluid flow far from any disturbances or obstacles.
Vortex Strength - (Measured in Square Meter per Second) - Vortex Strength quantifies the intensity or magnitude of a vortex in fluid dynamics.

STEP 1: Convert Input(s) to Base Unit

Freestream Density: 1.225 Kilogram per Cubic Meter --> 1.225 Kilogram per Cubic Meter No Conversion Required
Freestream Velocity: 6.9 Meter per Second --> 6.9 Meter per Second No Conversion Required
Vortex Strength: 0.7 Square Meter per Second --> 0.7 Square Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L' = ρ_∞*V_∞*Γ --> 1.225*6.9*0.7

Evaluating ... ...

L' = 5.91675

STEP 3: Convert Result to Output's Unit

5.91675 Newton per Meter --> No Conversion Required

FINAL ANSWER

5.91675 Newton per Meter <-- Lift per Unit Span
