Let's start the estimation with the drag: $$F_D = \frac{1}{2}\rho v^2 C_D A$$ Where $C_D A$ is going to be your form factor, depends on your drone design. Here are some example $C_D$ values $\rho$ is the air density. Here are some values, depending on temperature. If you increase the pressure to say 2x, the density also increases 2x. v is the velocity If ...
