A Shell and Heat Exchanger needs to be installed. Water from the turbine at 90 C is cooled to 80 C in a shell-tube HX using 150 kg/s of raw water from Power Plant Lake. The raw water temperature can increase by 2, 4, 6, or 10 C. Design a suitable HX for a 100 MW of heat load (If you chose a multi-module system design only one HX unit). The Heat exchanger tubes have to be shorter than 25 ft in length and the total pressure drop cannot exceed 20 psi.
