4.99 Refrigerant 134a enters the flash chamber operating at steady state shown in Fig. P4.99 at 10 bar, 36 C. with a mass flow rate of 482 kg/h. Saturated liquid and saturated vapor exit as separate streams, each at pressure p. Heat transfer to the surroundings and kinetic and potential energy effects can be ignored. (a) Determine the mass flow rates of the exiting streams, cach in kg/h, if p 4 bar.

(b) Plot the mass flow rates of the exiting streams, cach in

kg/h. versus p ranging from 1 to 9 bar.​
