Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Question

In a steady adiabatic flow through a duct with no shaft/electrical work and no change in elevation and potential energy, the
(A) enthalpy remains constant
B inlet enthalpy is greater than the outlet enthalpy
(C) outlet enthalpy is greater than the inlet enthalpy

modification is required so the pump can manage the changes?
A add a smaller pump in series to increase the energy (i.e., head)
B
replace the existing pump with a larger one with additional head capacity
add another pump in parallel
(D) a and b are feasible options
