Zero-lift Drag Coefficient Calculator by Mohit Kudal

Zero-lift drag is the combination of skin friction and form drag. It’s value depends on the body shape, size, flow conditions & inclination.

Where T = Thrust

W = Weight

σ = Density ratio

V = Velocity

k = Induce drag coefficient

S = Wing surface area

ρ = Density at height

ρ0 = Density at sea level
