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. R-134a enters the capillary tube as a saturated liquid at 50°C, and leaves at-12°C. Determine the rate of entropy generation in the capillary tube for a mass flow rate of 0.2 kg/s.
