question 10

Essay

Compare the osmotic power available from freshwater flowing at a rate of $1000 \mathrm {~m} ^ { 3 } / \mathrm { s }$ into the ocean (assuming an efficiency of $40 \%$ ) and the thermal power available from water flowing at $1000 \mathrm {~m} ^ { 3 } / \mathrm { s }$ through a heat exchanger and cooling by $5 ^ { \circ } \mathrm { C }$ (assuming an efficiency of $3 \%$ ).
