Question

5. [10 Pts] Compressed liquid water at 20 °C and 500 kPa is entering a heat exchanger at a rate of 5 kg/s. The water exchanges heat with a stream of R-134a that goes from superheated at 50 °C and 500 kPa to a binary mixture at 15 °C with a quality 20%. The exiting water is at 25 °C. According to the density difference, steam and liquid water are separated through two different exiting channels as shown below. If the exiting steam mass flux rate is 3.5 kg/s, what is the mass flux rate of R-134a? 20% quality R-134a @15 °C Water in (5 kg/s) Steam out (3.5 kg/s) Water out Superheated R-134a (50 °C, 500 kPa)
