An adiabatic capillary tube is used in some refrigeration
Chapter 7, Problem 187P(choose chapter or problem)
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 \(70^{\circ} \mathrm{C}\), and leaves at \(-20^{\circ} \mathrm{C}\). Determine the rate of entropy generation in the capillary tube for a mass flow rate of
\(0.2 \mathrm{~kg} / \mathrm{s}\).
