Water flows over a section of Niagara Falls at a rate of 2.2 * 106 kg/s and falls 65 m. What is the power wasted by the waterfall? The acceleration due to gravity is 9.8 m/s 2. Answer in units of W.

P = 1401.4 x 10⁶ W

Explanation:

Given that

Water flow rate m = 2.2 x 10⁶ kg/s

Height, h = 65 m

Acceleration due to gravity, g = 9.8 m/s²

The power P is given as

P = m g h

P=Power

m=Water flow rate

h=height

Now by putting the values in the above equation

P = 2.2 x 10⁶ x 9.8 x 65 W

P = 1401.4 x 10⁶ W

Therefore the power wasted will be 1401.4 x 10⁶ W.
