Two boilers, both operating at 13.8 bar a discharge equal amounts of steam into the same steam main. Steam from the first boiler is superheated at 488.15 K (215°C) and steam from the second is wet with a quality of 96%. Assuming adiabatic mixing and negligible changes in potential and kinetic energies, what is the equilibrium condition after mixing and what is SG for each kg of discharge steam?
