A V-V three-phase transformer is supplying a 50kVA balanced 3-phase load. What is the KVA rating of each transformer? If the power factor and voltage of the load is 0.8 lagging, 400V, what is the power factor and current of each transformer? Calculate the reactive power of each transformer.

On a average work day more than work place firs are reorted

Fluids at rest possess no flow energy. a)- true b)- false

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.
