Two flows of humid air (states A and B) should be mixed in a way that the relative humidity is OM > 40% at a temperature tm= 20 C. 60C 120kj/kg 60 50 C 0=0,1 400 kJ/kg. 80 kJ/kg 40C 40 0=02 30 C specific enthalpy, h 1+x [kJ/kg] 20 20 C = 0,4 60 kJ/kg saturated, = 1 A 10C = 0,6 0.8 40 kJ/kg More 20k/kg -10C. kJ/kg -20 5 10 15 20 25 water content, x [g/kg] a) Can the goal formulated for om and tM be achieved by just mixing two streams with the given states A and B? Give a brief explanation for your answer. b) What mass flow ratio m /m3 has to be chosen to adjust the aimed at temperature M = 20 C?
