Ocean Thermal Energy Conversion (OTEC) systems play a major
role in getting power from the ocean. Implementation of this
technology for power generation from ocean needs a critical study.
Therefore, you are asked to prepare a report on various critical
aspects of this system such as the appropriate principles, the
suitable conditions for the selection of a particular type of OTEC,
the development of various technologies in this field related to
the techno-economic feasibility, the popularity of technologies in
the international scenario and the restrictions in the capacity.
Moreover, you are asked to discuss on the critical factors to be
considered in the performance of this power plant, the analysis
procedure for the performance evaluation and selection of
performance parameters related to a place similar to Oman. Besides
a discussion on the challenges during implementation, a critical
comparison of this technology with geothermal power is also
expected to
decide on an investment plan.

A proposed Ocean Thermal Energy Conversion (OTEC) plant draws
heat from the ocean surface at 22°C and rejects heat to the water
near the ocean bed at 4°C. What is the highest thermal efficiency
the plant could achieve? [4] (b) Consider a system undergoing an
adiabatic process from a fixed state 1 to a fixed state 2. Use the
Second Law of Thermodynamics to prove that the maximum work is done
by the system if the process is reversible. [6]...
How do chemical reactions play a role in energy transfer?
a) Energy from the breakdown of glucose and other molecules in
animals is released as ATP, which transfer energy to other
reactions.
b) Energy from the breakdown of glucose and other molecules in
animals is released in the form of NADP, which transfers energy to
other reactions.
c) Energy is released in the form of glucose from the breakdown of
ATP molecules. These ATP molecules transfer energy from one
reaction...
Compare the similarities and differences of the following

Describe the main features of the Gulf Stream. What role does it
play in the ocean heat budget? What momentum balance did we use to
describe its flow and what momentum terms are involved? Sketch how
the sea level gradient influences Gulf Stream currents. Also sketch
how horizontal density gradients affect the Gulf Stream
current.
A nuclear power reactor produces 3GW of thermal power from the
fission of 235U for a period of 10 weeks and then it is shut down.
Note: All numerical answers are expected with 3 significant
figures. (a) Assuming 78% of the 200MeV released per fission event
is converted to heat, estimate the number of 235U nuclei fissioned
over the 10 week period. (b) 6 % of the 235U fission events produce
as a fission fragment some radioactive nuclide X (e.g....
in a paragraph, What role does the Great Ocean Conveyor Belt or
thermohaline circulation play in the carbon cycle? Describe how it
works to store carbon and its importance. What risks do melting
continental glaciers present to this function? Why?
How does the renal and endocrine system play a role in getting
tissues oxygenated? Or in other words, how does the renal and
endocrine system help maintain homeostasis through the oxygenation
of tissues? Consider how tissue oxygenation goes up or down and how
each system makes/contributes to a change that helps maintain
homeostasis.
