Choose the correct statement. The cathode is the electrode where the oxidation takes place. Both oxidation and reduction may take place at the cathode, depending on the cell. The cathode is always positive. The anode is always negative.

A double pipe heat exchanger is to be designed to heat 1 kg/s of a cold fluid from 30°C to 60°C using 2 kg/s of a hot fluid at 100°C. The two streams have equal specific heat capacities and overall heat transfer coefficient.
