Question

In a counter current single pass heat exchanger, cooling water enter at 0°C and leaves at 20°C. Hot water enters from the other side at 60°C at a flow rate which is half of the cooling water flow rate. Assuming there is no heat loss, what is the Log Mean Temperature Difference?

Explanation

Mechanistically, thermodynamics and heat transfer involves ΔU, ΔH, LMTD and w=PΔV govern chemical and heat exchange processes. This validates 34.8 because it explains energy changes and heat transfer in biological and engineering systems, a pattern repeatedly demonstrated in biophysics and techniques research.
