Explain and sketch, the SECOND LAW ?OF THERMODYNAMIC

The rate of entropy transfer associated with heat transfer from a closed system operating at steady state to its surroundings must be equal to the rate of entropy production due to irreversibilities within the system. O True O False eTextbook and Media Save for Later

answer 99 and 100

Entropy generation outside system boundaries can be accounted for by writing an entropy balance on an extended system that includes the system and its immediate surroundings.

Bernoulli's principle is an example of which law of thermodynamics. Explain why?

Third law of thermodynamics is concerned with: a. the value of absolute entropy b. energy transfer c. direction of energy transfer d. none of these

The system shown is at steady state, steady flow. At inlet 1, the rates of kinetic energy, potential energy and enthalpy entering the system are: KE1 = 0.10 kW, PE1 %3D 0.22 kW, and H1 = 27.0 kW. At inlet 2, the rates are: KE2 = 0.23 kW, PE2 = 0.18 kW, and H2 = 18.0 kVW. At exit 3, the rates are: KE3 = 0.52 kW, PE3 = 0.28 kW, and H3 = 7.0 kW. If the system gives up 5.0 kW of heat to the surroundings, what is the rate of work transfer of the system? Express the answer in kw. %3D KE3 PE3 1 KE. РЕ H. KE2 PE2 На Control volume boundary

If a closed system undergoes a process for which S2=S1, the process must be internally reversible. - True or False One of the Carnot principles states that all power cycles operating between the same two thermal reservoirs have the same thermal efficiency. - True or False One statement of the second law of thermodynamics recognizes that the extensive property entropy is produced within systems whenever internal irreversibilities are present. - True or False
