An adiabatic mixing chamber with operating pressure of 180 kPa is used to mix cold water and hot water. The hot water enters at 80°C with mass flow rate of 4.1 kg/s. The cold water enters the chamber at 39°C and the mixture leaves at a temperature of 45°C. Determine (a) the mass flow rate of the cold water and (b) the rate of entropy generation during this process.
