Liquid water at 15 ℃ is heated by mixing it with saturated steamat the same pressure. Liquid water enters a chamber at a rate of4.3 kg/s and saturated steam enters at a rate of 0.17 kg/s. Themixture leaves the mixing chamber as a saturated liquid at 40℃. Ifthe surroundings are at 15℃, determine (a) the temperature of thesaturated steam entering the chamber, (b) the exergy destructionduring this mixing process, and (c) the second-law efficiency ofthe mixing chamber. Hint: You must look up the second-lawefficiency of a mixing chamber.
