Problem: At 8:00AM a lighthouse is north of a ship. Thirty minutes later the lighthouse bears N 40°45' E from the same ship. If the ship is sailing westward at a speed of 15 km/hr, find the distance of the ship from the lighthouse after thirty minutes. a. 11.49 km

of Line Load Capacitor A three-phase system is represented as shown above. Line: 42in 42 in Line is selected to be AAC #336.4 with ampacity of 513A Diameter of each conductor is d= 0.666 in or 5.03 mm Distance between conductors D= 42 in The length of the line is 1= 20 km Resistance per unit length is r= 0.63 Ohms/1000 ft (there are 0.3048km in 1000ft) Load: P (kW) = 1600 Power factor = 0.75 Voltage at the load V = 13.8 kV

Find out the field strength at 1 on away from an isotopic station of 1 kW power.

Question A 100 MVA generator operates on full-load of 50 Hz frequency. The load is suddenly reduced to 50 MW. The steam valve begins to close only after 0.4 s and if the value of the inertia constant H is 5 s, then the frequency at 0.4 s is nearly
