As an engineer at Tata Motors, you are asked to design an engine cooling system. The system should be capable of removing \(20 \mathrm{~kW}\) of energy from the engine of a car at a speed of \(75 \mathrm{~km} / \mathrm{h}\) and ambient temperature of \(35^{\circ} \mathrm{C}\). The system consists of radiator, fan and flow arrangement. The dimensions of the engine are given. The distance between the engine of the car and the radiator must not exceed 2.0 \(\mathrm{m}\) and the dimensions of the radiator must not exceed \(0.45 \times 0.45 \times 0.15 \mathrm{~m}^{3}\).
