Answer:
The rate of irreversible loss will be "55.22 MW".
Explanation:
The given values are:
Elevation,
h = 120 m
Flow of water,
Q = 100 m³/s
Efficiency,
= 80%
i.e,
= 0.8
Efficiency turbine,
= 50 MW
Now,
Without any loss,
The power generated by turbine will be:
⇒ [tex]P=\delta gQh[/tex]
On substituting the values, we get
⇒ [tex]=1000\times 9.8\times 100\times 120[/tex]
⇒ [tex]=117.72 \ MW[/tex]
Power generated in actual will be:
= [tex]\frac{50}{0.8}[/tex]
= [tex]62.5 \ MW[/tex]
Hence,
Throughout the piping system,
The rate of irreversible loss is:
= [tex]Power \ generated \ by \ turbine-Power \ generated \ in \ actual[/tex]
= [tex]117.72-62.5[/tex]
= [tex]55.22 \ MW[/tex]
