Aphase separator receives 2.5 kg/s of r134a at 0 c with a quality of 60%. saturated liquid exits through the separator bottom at a rate of 1.5 kg/s. saturated vapor exits through the separator top at a rate of 0.25 kg/s. the phase separator is initially filled entirely with 0 c saturated liquid. a) what heat transfer is required to get mixture within the phase separator to 50% quality? report your answer in kj. b) what mass of r134a enters the separator? report your answer in kg.
