Modified Newton’s sine-squared law is a formula that improves the accuracy of Newton’s sine-square law of air resistance for predicting the aerodynamic forces on a body moving in a fluid. The modified law accounts for the effects of the body shape and the flow separation by introducing a correction factor called the Newtonian pressure coefficient.
- Pressure coefficient (Cp)
- Maximum pressure coefficient (Cp,max)
- Angle between a normal to the surface (𝜃) in rad
