Two streams are mixed in an adiabatic mixer, as shown in the figure. It is known that: Stream 1 is saturated liquid/saturated vapour mixture at 1 bar with flow rate 0.71 kg/s and quality 0.20 Stream 2 is superheated vapour at 1 bar and 440C Stream 3, the product stream, is a saturated liquid/saturated vapour mixture at 1 bar with quality 0.80 Neglect kinetic and potential energy changes and calculate the mass flow rate of the superheated vapour stream, in kg/s. (2) Mixer Answer: * (0.844)
