A cylinder glass tubing 2.8 cm. inside diameter and 90 cm long with one end closed is immersed vertically with the open end down into a tank of cleaning solvent (sp.gr. = 0.73) until only 5 cm. of its length remain above the liquid surface. If the barometric pressure is 1 kg/cm? and neglecting vapor pressure and the weight of the glass tubing, what is the force in Newton, required to maintain equilibrium?
