You are designing a freezer that requires the production of R-134a with T = -30°C and a quality of 40%. The feed temperature, to the throttle, is 30°C. If the diameter of the tube exiting the throttle is 1 cm, calculate the following: a. Upstream diameter [for A(v2) = 0] b. Required upstream condition of the R-134a (pressure and state). c. Pressure drop, AP, across the throttle.
