How many poles should a 60-hz generator have, if it is connected to a turbine operating under a design head of 3000 ft with a flow of 82 cfs? assume turbine specific speed and efficiency 3 and 84 percent respectively.

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

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
