The equivalent circuit per-phase parameters for a 220 V, 50 Hz, three-phase, star-connected, 4-pole, induction motor is: R1 0.22 0, R2' = 0.15 0. The inductor motor has a slip of 4% and the full load current has a magnitude of 61 A. The mechanical losses (windage and friction) and the iron losses are 610 W are 420 W respectively. The input power is 36300 W. Determine the following when the motor operates at full load at rated speed: A. the synchronous speed RPM B. the rotor speed in RPM C. the efficiency of the motor in percentage D. the output torque in N-m for a slip of 8%.

Hi, I need the the answer for question 7.53. It would help me very much
3.3 Find the Laplace transform of the following signals and in each case determine the corresponding region of convergence: 238/ 3.10 PROBLEMS 231 (a) the signal x (t) = e¬atu(t) – eat u(-t) when (i) œ > 0, (ii) a → 0, (b) a sampled signal N-1 x1(t) = e-"8(t – n), е n=0 (c) the "stairs to heaven" signal s (1) 3D > и (г — п), n=0 (d) the sinusoidal signal v(t) = [cos(2(t – 1)) + sin(27t)]u(t – 1), (e) the signal y(t) =1²e-2 u (1) using that x (t) = 1²u(t) has X (s) = 2/s³. Answers: (a) As a → 0, x(t) =u(t) – u(-t), has no Laplace transform; (b) the ROC is the whole s-plane; (c) S(s) = 1/(s(1 – e-s)); (e) Y (s) =2/(s+2)³.

Automatic lawn sprinkler systems use a digital system to control the opening and closing of water valves. A sprinkler system usually supports several different zones such as the backyard, left side yard, right side yard, front yard etc. Only one zone's value can be opened at a time in order to remain enough water pressure in the sprinklers in that zone. suppose a sprinkler system supports up to 8 zones. Typically, a sprinker system is controlled by a small, inexpensive microprocessor executing a program that opens each value only at specific times of the day and for specific durations. suppose the microprocessor only has 4 output pins available to control the valves, not 8 outputs as required for the 8 zones. We can instead program the microprocessor to use 1 pin to indicate whether a valve should be opened, and use the 3 other pins to output the active zone (0,1....7) in binary. thus we need to design a combination circuit having 4 inputs, e, and a,b,c (the binary value of the active…

Solve number 1. You can use other problems on the internet as long as you’re going to provide an explanation on how to solve it.
4. A decorative display uses inexpensive mass produced colored lights having constant failure rate of 1000 per million per day. Assume that such a display is designed with 2000 such lights that are all turned on at the same time. The lights are so connected that failure of one does not affect the operation of others. a) How many lights can be expected to still be operational after 90 days? b) Determine the mean time to failure of any given light. c) Determine the probability that any given light will fail within the first 100 days after turn on and also that 20 lights will do likewise. d) Repeat part c) replacing 1000 days for 100 days. e) Determine the time that can be expected to elapse (from turn on) before the display has only one operational light left.
