Problem 3- Clausius InequalityThe table below shows different processes occurring in a power cycle operating steadilybetween a hot and cold reservoirs at T₁ = 1800 K and T₁ = 600 K, respectively. Use the ClausiusInequality to evaluate and classify each case as reversible, possible, or impossible. Yourconclusion has to be based on the result of the evaluation of the inequality. Also, for each case,indicate if there is a violation of the first and/or second law of thermodynamics.Case Q₁ (kJ/s) Q₁ (kJ/s) Wnet (kW) Conclusion500100350500200250500150350500200300abCd

Water is compressed adiabatically, but inefficiently, from p1 = 150 kPa and T1 = 160 ∘C to a pressureof p2 = 700 kPa. A throttle valve is connected to the outlet of the compressor and has a temperature reading atits outlet of T3 = 440 ∘C at atmospheric pressure (1 bar). If the compressor operates at steady state, stray heattransfer can be neglected, and the changes in kinetic and potential energy are negligible, determine the isentropicefficiency of the compressor, in percent.
Answer the following true or false. Explain. (a) A process that violates the second law of thermodynamics violates the first law of thermidynamics. (b) When a net amount of work is done on a closed system undergoing an internally reversible process, a net heat transfer of energy from the system also occurs. (c) One corollary of the second law of thermodynamics states that the change in entropy of a closed system must be greater than zero or equal to zero. (d) A closed system can experience an increase in entropy only when irreversibilities are present within the system during the process. (e) Entropy is produced in every internally reversible process of a closed system. (f) In an adiabatic and internally reversible process of a closed system, the entropy remains constant. (g) The energy of an isolated system must remain constant, but the entropy can only decrease.
