So, I've been given that archimedes principal for an atmospheric layer of gas on a planet is
dP/dr = -rho*g
where g is constant.
For a vanderwaals gas,
P = rhot*R*T - a*rho^2
I used the quadratic formula & solved for rho and put that into the dP/dr equation. getting...
dP = [((-RT +/- ((RT)^2 - 4aP)^.5) / 2a ] dr
now i need to separate the variables and integrate, to get P as a function of r, but how do i get P out of the right side of the equation?
Thanks!
