13. An insulated chamber receives 2kg/s R-134a at 1 MPa, 100 ° c in a line with a low
velocity. Another line with R-134a as saturated liquid, 600c flows through a valve to the
mixing chamber at 1 Mpa after the valve. The exit flow is saturated vapor at 1Mpa flowing
at 20-m/s. Find the flow rate for the second line.
Solution:
Q=0; W=0;
