A. an ideal vapor compression refrigeration cycle with r-134a as the working fluid. saturated vapor enters the compressor at -10°c and saturated liquid leaves the condenser at 2 mpa. the mass flow rate through the unit is 10 kg/min. determine the refrigeration capacity in tons. b. the volumetric analysis of a gas mixture shows that it consists of 70% nitrogen, 20% carbon dioxide, and 10% carbon monoxide. if the pressure and temperature of the mixture is 140 kpa and 40°c, what is the percent of carbon monoxide by mass?
