Three ideal transformers are rated to deliver 460 kVA at 380 V rms to three customers, one transformer is shown in Figure 45. The first customer's load is purely resistive (i.e., pf = 1), the second customer's load has a power factor of 0.6 lagging, the third customer's load has a power factor of 0.9 leading. What is the maximum total real power the three customers can receive? (enter your answer in whole kW, no decimal)

2) Consider two Conducting Rings with radii ($r_1$) and ($r_2$) respectively. The rings share the same central axis & their centers are separated by a distance (D). If ($r_1 >> r_2$), find the following: a) $M_{21}$ =? $( rac{dI}{dt})$ b) If the current doubles every second ($ rac{dI}{dt} = 2I_1$), find the voltage induced in ring 2 magnitude of c) If ring 2 has an internal resistance (R), find the magnitude of the current induced ($I_2$=?) $r_1 >> r_2$

QUESTION 3 [15 MARKS] A generating set is arranged on board a ship with its axis parallel to the longitudinal centreline of the ship. The revolving parts have a mass of 1400 kg, a radius of gyration of 400 mm, and 2 revolve at 420 r/min. If the ship steams at 36 km/h, round a curve of 180 m radius, find the magnitude and the sense of the gyroscopic couple transmitted to the ship.

5. Charge Account Validation Design a program that asks the user to enter a charge account number. The program should determine whether the number is valid by comparing it to the following list of valid charge account numbers: 5658845 4520125 7895122 8777541 8451277 1302850 8080152 4562555 5552012 5060652 7825877 1250255 1005231 6545231 3852085 7576651 7881200 4581002 These numbers should be stored in an array. Use the sequential search algorithm to locate the number entered by the user. If the number is in the array, the program should display a message indicating the number is valid. If the number is not in the array, the program should display a message indicating the number is invalid.
