A Y connected synchronous generator is delivering a delta connected three-phase load with impedance 11 j8 ohms per leg. The line-line voltage at the load terminals is 13.8 kV. The generator has negligible rotor resistance and a synchronous reactance of 1.5 ohm. What is the active power delivered to the load

What precautions should you take to prevent injuries when dealing with heavy loads?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

At 12 noon, the count in a bacteria culture was 400; at 4: 00 pm the count was 1200 let p(t) denote the bacteria cou population growth law. find: (a) an expression for the bacteria count at any time t (b) the bacteria count at 10 am. (c) the time required for the bacteria count to reach 1800.
