A stack gas from a combustion reaction is given off of a furnace which contains mole fractions of 0.740 N2, 0.10 CO2, 0.03 CO, and the balance H2O. This stack gas must be cooled before exiting to the atmosphere. Let us assume that hot gas is given off at 900ºC. This hot gas and cooling water at a temperature of 15ºC enter a heat exchanger. The hot gas exits the heat exchanger at a temperature of 50ºC. If 13000 lbmol/hr of the gas enters the heat exchanger, you can assume steady state process, the exchanger is perfectly insulated, and the exiting water is at a temperature of 45ºC, what is the mass flowrate of water required?

Question
A stack gas from a combustion reaction is given off of a furnace which contains
mole fractions of 0.740 N2, 0.10 CO2, 0.03 CO, and the balance H2O. This stack gas must be
cooled before exiting to the atmosphere. Let us assume that hot gas is given off at 900ºC. This
hot gas and cooling water at a temperature of 15ºC enter a heat exchanger. The hot gas exits the
heat exchanger at a temperature of 50ºC. If 13000 lbmol/hr of the gas enters the heat exchanger,
you can assume steady state process, the exchanger is perfectly insulated, and the exiting water is
at a temperature of 45ºC, what is the mass flowrate of water required?
