A car radiator design consists of fin arrays fitted on four tubes with serpentine configuration. The total cooling water flows at 180 kg/min and receives heat from the engine at 90°C. Ambient air at a temperature range of 22°C -30°C is blown at 5 kg/s to the radiator at a perpendicular direction to the cooling water flow path. For this compact cross-flow heat exchanger, determine the effect of ambient temperature increase to the exit temperature of the cooling water. Also, what would be the effect to engine cooling if the ambient temperature changes? The fin-side surface area is A, 50 m² and the fin-side overall heat transfer coefficient, U = 230 W/m².K. The specific heat for the air and water are 1.005 kJ/kg.K and 4.18 kl/kg.K respectively.
