Assume that Alternator A is supplying power to a load and that Alternator B is to be parallel to Alternator A. After the paralleling has been completed, what must be done to permit Alternator B to shard the load with Alternator A?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
