An adiabatic capillary tube is used in some refrigeration systems to drop the pressure of the refrigerant from the condenser level to the evaporator level. The R-134a enters the capillary tube as a saturated liquid at 60 oC. It is required that at the evaporator inlet the quality should be 20 percent. Determine:

a) Exit temperature of the capillary tube

b) Average Joule Thomson coefficient
