An inventor proposes an engine that operates between the 27 deg c warm surface layer of the ocean and a 10 deg c layer a few meters down. the claim is that this engine can produce 100 kw at a flow of 20 kg/s. is this possible?

Engine not possible

Explanation:

source temperature T1 = 300 K

sink temperature T2= 283 K

therefore, carnot efficiency of the heat engine

η= 1- T_2/T_1

= 0.0566

= 5.66%

claims of work produce W = 100 kW,  mass flow rate = 20 kg/s

= 1421.2 kW

now

now

=7%

clearly, efficiency is greater than carnot efficiency hence the engine is not possible.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
