A solution with inlet temperature, specific heat, and flow rate of 90 [°C], 3.85(kJkgK), and 1.0(kg/s) respectively, is cooled in a countercurrent flow heat exchanger with water whose flow rate temperature and specific heat are 2.0 [kg/s), 25°C) and 4.19 [kW/kgK), respectively. Determine the exit temperature the fluid.
