A 12.47 kV, three-phase distribution feeder is 1.9 miles long and can wheel up to 5.5 MVA. Oriole conductors were hung using an equilateral triangular spacing scheme, with conductor spacing of only 6 inches. 1. Considering the very narrow spacing between conductors, determine whether a short t-line model is sufficient to represent the feeder or if a medium model is required. Do so by comparing the ABCD coefficients for each model, expressed in SI units. Assume a 25 °C operating temperature.
2. Using the most appropriate model, calculate the voltage regulation when a rated load with 0.95 lagging power factor is attached.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
