Problem 197EUP
An insulated mixing chamber, as shown in Fig. P4.110, receives 4 lbm/s of R-134a at 150 lbf/in.2, 220 F in a line with lowvelocity. Another line with R-134a of saturated liquid at 130 F flows through a valve to the mixing chamber at 150 lbf/in.2 after the valve. The exit flow is saturated vapor at 150 lbf/in.2 flowing at 60 ft/s. Find the mass flow rate for the second line.
