Question

This is an equation in the second edition “dynamics of flight” book. I am trying to figure out the equation. I know that v=velocity, but I’m not sure about what P is. Either dynamic pressure, or some Greek letter standing for something else.

Answer 1

we know that

dynamic pressure formula is

$P=\frac{1}{2} \rho v^2$

$\rho = rho$

that is density

P is pressure

v is velocity
