Design a heat exchanger for a chemical process that requires the transfer of heat from a hot stream containing molten sodium at 1100°C to a cold stream containing water at 25°C. The hot stream inlet flow rate is 1000 kg/hr, and the cold stream outlet temperature should be limited to a maximum of 70°C. The heat transfer coefficient for the tubeside and shellside is 1000 W/m²K and 500 W/m²K, respectively. The design should minimize the size and cost of the heat exchanger while meeting the thermal requirements of the process.

Calculate the resistance of a electrochemical cell at 25°C if the standard reduction potential of the anode is -1.36 V and the standard reduction potential of the cathode is +0.40 V. The solution contains 0.1 M CuSO4 and 0.01 M ZnSO4. The distance between the two electrodes is 5 cm and the cross-sectional area of each electrode is 2.5 cm².
