Modified Newtonian theory Calculator

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)
  • Pressure coefficient (Cp) Maximum pressure coefficient (Cp,max)
  • Angle between a normal to the freestream direction (Φ) in rad
