1. The problem statement, all variables and given/known data

A nuclear power plant on the Connecticut River produces 2.00x10^2 megawatts of power, but also releases 1.00x10^11 kJ/day of waste heat into the river. assume that the average rate of flow of the river is 9.00x10^4 kg/s. a. What is the maximum temperature increase in the river water that could be caused by the plants cooling system? b. The construction of four additional nuclear power plants along the river has been proposed. What is the total increase in the temperature of the river that could result if the plants are built? Could this change cause serious damage to the ecological structure of the river?

2. Relevant equations

Not a clue, this is where the help is needed. deltaTxmxC=Q

3. The attempt at a solution

Converted kJ to regular joules, used the equation for specific heat, but I know I'm missing steps in the process.

This is the only equation my teacher has provided me with, should i possibly be using a different equation.

The equation you posted is a start, but you'll need to adjust it a bit since you don't have Q or m (kJ and kg) but a rate of energy transfer and a rate of mass transfer (kJ/day and kg/s)
