The results of the no-load and blocked-rotor tests on a 3-φ, y-connected, 60-hz, 2000-hp induction machine with a stator phase resistance of 0.02 ω are as follows: no-load test: total input power = 11.617 kw line-to-line voltage = 2300 v line current = 26.55 a blocked-rotor test: total input power = 319.22 kw line-to-line voltage = 462.68 v line current = 407.75 a frequency = 60 hz (a) calculate the parameters r1, x1, xm, r’2, and x’2 of the approximate equivalent circuit. (b) draw the equivalent circuit of the induction motor using the parameters from 3(a).

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
