In air-conditioning systems, streams of cold and warm air are mixed to get air with the right temperature. Consider a mixing chamber into which cold air enters at 8 degree C and 100 kPa at a rate of 0.55 m3/s and warm air enters at 30 degree C and 100 kPa. The ratio of mass flow rates of warm to cold air streams is 1.6. Using variable specific heats, determine the mixture temperature leaving the mixing chamber
