A throttling valve in a refrigerator receives saturated liquid R-134a at 800 kPa, and exhausts the R-134a as a saturated mixture at 180 kPa.
(a) Assuming no changes in kinetic energy of the R-134a, determine the quality of the exiting mixture. (b) For the same inlet conditions, use your throttling device model and plot the exit quality of the R-134a as the exit pressure is varied between 100 kPa and 700 kPa. Given: P1 = 800 kPa; x1 = 0 (saturated liquid); P2 = 180 kPa R-134a (Take State 1 as the inlet, State 2 as the outlet.) Assume: Q?=W?=0. For a throttling valve, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?KE = ?PE = 0
