A 20 kW, 6-pole, 50-Hz, 3-phase slip-ring induction motor runs at 960 revolutions per minute on full load with a rotor current per phase of 40 A. Allowing 300 W for the copper loss in the short circuiting gear and 1100 W for mechanical losses, the resistance per phase of the three-phase rotor winding will be _____
Ω. (upto three decimal places)
