The lowest flow in the Menominee River in July is about 40 m3/s. If the river temperature is 18°C and a power plant discharges 2 m3/s of cooling water at 80°C, what is the final river temperature after the cooling water and river have mixed?

is the final river temperature after the cooling water and river have mixed.

Explanation:

Final river temperature after mixing using energy energy balance equation

Where, is specific heat at constant pressure, change in temperature, is flow in the river,is the flow of cooling water from plant, final required temperature after mixing cooling water and river water,and, is density of water.

From Diagram

While substituting,

and

Finally, the temperature after the mixing of cool water and river is .

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.
