Answer: A) Gradually decrease
Explanation:
The convection value of heat transfer rate are gradually decreasing with the flow of the heat. Flow in a circular pipe, flow direction does not change in the velocity path. The average of the coefficient of heat transfer and the number of pipes are needed and the effects are get neglected so that is why the flow are fully developed.

Answer:
A).False
B).False
C).False
D).True
Explanation:
As we know that ,when system and surrounding return in initial position without leaving any effect on the surrounding then it is called reversible process.
Option A is false because this is not a adiabatic process.
Option B we know that work is path function and it depends on the path even process is reversible or irreversible.That is why option B is false.
Option C is false because we can not say that entropy change of system is zero.The entropy of system can be increase or decrease we can not say anything.
Option D is true because the entropy of universe is always zero for a reversible process.Universe is the summation of surrounding and system.
