When the Glen Canyon hydroelectric power plant in Arizona is running at capacity, 690 m3 of water flows through the dam each second. The water is released 220 m below the top of the reservoir. If the generators that the dam employs are 90% efficient, what is the maximum possible electric power output?Express your answer with the appropriate units.

The maximum electric power output is

Explanation:

From the question we are told that

        The capacity of the hydroelectric plant is

         The level at which water is been released is

        The efficiency is  0.90

The electric power output is mathematically represented as

Where   is the potential energy at  level h which is mathematically evaluated as  

and    is  the potential energy at ground level which is mathematically evaluated as  

So  

here  

where V is volume  and   is density of water whose value is  

 So  

substituting values  

The maximum possible electric power output is

substituting values
