Two vertical plates submerged partially in a wetting liquid form a wedge with a very small angle `delta varphi`. The edge of this wedge is vertical. The density of the liquid is `rho`, its surface tension is `alpha`, the contact angle is `theta`. Find the height `h`, to which the liquid rises, as a function of the distance `x` from the edge.
