A three-phase, Y-connected, 4.16 k VLL feeder has R = 50 m and X = 30 m,

A three-phase, Y-connected, 4.16 k_VLL feeder has R = 50 mΩ and X = 30 mΩ, both per phase per 1000-ft. length. Determine the voltage drop in the feeder at 

(1) 0.8 power factor lagging and 

(2) Unity power factor. Establish the V_drop per 1000-ft. run for a 1-MVA load so that it can be easily reused for various megavolt-ampere loading and feeder lengths.
