Answer:
The fall will produce 1.04×10³ MW power
Explanation:
Power: This is the rate at which work is done. The S.I unit of power is Watt (W)
P = Energy/time
P = mgh/t
P = μgh..............................................Equation 1.
Where P = power, μ = the mass rate of water flow, h = height, g = acceleration due to gravity.
Given: μ = 1.66×10⁶ kg/s, h = 128 m, g = 9.81 m/s².
Substituting these values into equation 1
P = (1.66×10⁶×128×9.81)/2
Note: Half the potential energy of the water were converted to electric energy.
P = 1.66×10⁶×64×9.81
P = 1042.21×10⁶
P = 1.04×10⁹ W
P = 1.04×10³ MW
Thus the fall will produce 1.04×10³ MW power
