Liquid water at 20 Celcius degree is heated in a mixing chamber by obtaining a mixture with a saturated steam as shown in Fig. 2. As shown in this figure, the liquid water, and the saturated vapor enter this chamber with mass flow rate values of 7.2 kg/s and 0.35 kg/s, respectively. On the other hand, the mixed fluid leaves this chamber at 50 Celcius degree, as a liquid. If the ambient temperature of the surroundings are at 15 Celcius degree, determine, a) The temperature of the saturated vapor which is entering this mixing chamber, b) The exergy destruction during this mixing process using the entropy balance, c) The exergy destruction during this mixing process using the exergy balance,
Liquid water at 20 Celcius degree is heated in a mixing chamber by obtaining a mixture with a
saturated steam as shown in Fig. 2. As shown in this figure, the liquid water, and the saturated vapor
enter this chamber with mass flow rate values of 7.2 kg/s and 0.35 kg/s, respectively. On the other
hand, the mixed fluid leaves this chamber at 50 Celcius degree, as a liquid. If the ambient temperature of the
surroundings are at 15 Celcius degree, determine,
a) The temperature of the saturated vapor which is entering this mixing chamber,
b) The exergy destruction during this mixing process using the entropy balance,
c) The exergy destruction during this mixing process using the exergy balance,
d) The second law-efficiency of this mixing chamber device, considering this ambient temperature
value of 15 Celcius degrees.
