Consider the possible design of an OTEC facility that has an electrical output comparable to an average nuclear power plant $\left( \mathrm { e } . g . , 1 \mathrm { GW } _ { \mathrm { e } } \right)$. Assume a turbine/generator efficiency of $90 \%$.
(a) If the surface temperature is $23 ^ { \circ } \mathrm { C }$ and the cold reservoir is at $4 ^ { \circ } \mathrm { C }$, what is the efficiency?
(b) What is the total flow rate of water needed?
(c) Compare the result of part (b) to the flow rate needed for a $1 \mathrm { GW } _ { \mathrm { e } }$ hydroelectric facility with a head of $200 \mathrm {~m}$.
