Saturated liquid water at 20 degree Celsius enters a mixing chamber at a rate of 2.5kg/s. At the same time, hot water steam at 200kPa and 150 degree Celsius enters the mixing chamber at a rate of 0.2kg/s. After mixing in the chamber, all the water leaves the chamber as saturate liquid at 60 degree Celsius. Determine the heat loss rate of this mixing chamber. If all the heat loss to the surrounding at 25 degree Celsius, determine the rate of total entropy generation during this mixing process.
