Answer:
4.29%
Explanation:
Given:
Density of water, ρ = 1000 kg/m³
elevation change of Δz = 800 m
work per unit mass delivered, Wp = 8,200 J/kg
Now,
The percent irreversibility =
where,
also,
Where, g is the acceleration due to the gravity
on substituting the values, we get
or
or
Therefore,
The percent irreversibility =
on substituting the values, we get
The percent irreversibility =
or
The percent irreversibility = 4.29%
