In several parts of the world there exist ocean currents ofdiffering temperature

In several parts of the world there exist ocean currents ofdiffering temperatures that come into close proximity. It has beenproposed that work can be obtained from these ocean currents usinga heat engine that operates between the warm current as a sourceand the cold current as a sink. Assuming that the system may besimplified into two channels of water in close proximity flowingcocurrently or countercurrently. Furthermore assume that no mixingoccurs between the two streams and that the effect of heatconduction is negligible. If the flow of the cold stream is 16 x106 m3/s and its initial temperature is 278 K while the flow of thehot stream is 20 x 106 m3/s and its initial temperature is 300 Kcalculate the maximum power (Carnot Engines) attainable from thesestreams if the two steams flow (a) cocurrently and (b) if they flowcountercurrently. What is the minimum approach temperature and weredoes it occur?
