Question

hey all of u please solve it anyone its important for me
In question 18
Calculate amount of power generated

Answer 1

Answer:

1.8 × 10^6 W

Explanation:

Kinetic energy at the surface = 2 × 10^6 J/s

this Kinetic energy of water is converted into mechanical energy of turbine and electricity is generated.

efficiency of turbine = 90%

energy generated per sec by the turbine

= 2 × 10^6 × 90/100 = 1.8 × 10^6 J/s

hence, the power generated = 1.8 × 10^6 W
