g A power generation system with a turbine and a generator is located at a dam, where the water falls from 124.896 m height to the turbine. Assuming turbines having 100% efficiency, what should be the flow rate of water (in kg/s) to produce 5.776 MW of power

Respuesta :

Answer:

[tex]\dot m = 4830.240 kg/s[/tex]

Explanation:

Given data:

height of water fall = 124.896 m

efficiency = 100%

Power = 5.776 MW

flow rate of water can be calculated as

[tex]\dot W = \eta \dot m gh[/tex]

where

[tex]\dot m [/tex]is flow rate of water

plugging all value in above relation

[tex]5.776 \times 10^6 = 1.00 \times \eta \times 9.81 \times 121.896[/tex]

solving for flow rate we get

[tex]\dot m = 4830.240 kg/s[/tex]
