Powerplant cooling water with a temperature of 35 °C and a flowrate of 10 m3/s is discharged into a river with a temperature of 10 °C and a flowrate of 50 m3/s.
a) What will the new temperature of the river be downstream of the mixing point? Draw and label your figure and state any assumptions.
b) Using your knowledge of Henry’s law to justify your answer, how will this change in river temperature influence the amount of oxygen gas dissolved in the water?
