To periodically accumulate an additional volume of water obtained when the temperature changes, expansion tanks communicating with the atmosphere are connected to the water heating system at its upper point. Determine the smallest volume of the expansion tank when partially filled with water. Permissible fluctuations in water temperature during breaks in the operation of the furnace ?t = 95 - 70 = 25°C. The volume of water in the system is W = 0.55 m3.
