When a vertical capillary of length l with a sealed upper end was brought in contact with the surface of a liquid, the level of this liquid rose to the height h . The liquid density is rho , the inside diameter the capillary is d , the contact angle is theta , the atmospheric pressure is rho_(0) . Find the surface tension of the liquid. (Temperature in this process remains constant.)
