Ammonia enters a control volume operating at steady state at p1 = 16 bar, T1 = 328 0C, with a mass flow rate of 1.5 kg/s. Saturated vapor at 6 bar leaves through one exit and saturated liquid at 6 bar leaves through a second exit with a volumetric flow rate of 0.10 m3/min. Determine: (a) the minimum diameter of the inlet pipe, in cm, so the ammonia velocity at the inlet does not exceed 18 m/s.
(b) the volumetric flow rate of the exiting saturated vapor, in m^3/min.
