Question

Electric power is to be generated by installing a hydraulic turbine-generator at a site 120 m below the free surface of a large water reservoir that can supply water at a rate of 1900 kg/s steadily. Determine the power generation potential

Answer 1

P = 2234400 Watt

Step-by-step explanation:

Power generation is given as rate of work done

Here the turbine generator is located at 120 m below the free surface

So here rate of work done is given as rate of potential energy

`Power = (dw)/(dt)`

`Power = (mgh)/(t)`

so we have

`Power = ((dm)/(dt))gh`

now we have

`Power = 1900(9.8)(120) = 2234400 Watt`

so the power generation potential will be 2234400 Watt
