Heat Rejection Analysis for Pond/Lake

I need an expert to calculate heat rejection into a pond or lake. You will need to calculate the volume of the lake, its surface area, and the temperature variations, as well as the flow rates for the heat exchanger.

I have a comprehensive set of data available:
- Lake dimensions including volume and surface area
- Temperature measurements
- Flow rates for the heat exchanger

Ideal skills for this job include:
- Strong background in environmental engineering or thermodynamics
- Proficient in using empirical formulas, simulations, and analytical calculations
- Experience in conducting similar calculations for heat exchangers

Please note that I have not specified a preferred method for calculating the heat rejection, so the successful freelancer will have the flexibility to choose the most effective approach.
