For the specific volume of wet steam, SV=(1-Xv)SV (liq) + XvSV (vapor). Entropy is also calculated this way. If a tank initially has 5kg of wet steam with mass of vapor =1 kg at 100 kPa, and it is heated such that saturated vapor remains in the tank. Assuming that the process is in constant volume, what will be the entropy change of the steam (Kj/K)?

please help with following problems: (a) Determine the heat exchanged between the piston/cylinder and the heatreservoir in kJ. Is heat added to the system or rejected to the heatreservoir?  (b) Determine the change of entropy of the system in kJ/K. Is the resultreasonable?    (c) Determine the entropy generation in kJ/K (change of entropy of thesystem+entropy change of the heat reservoir).

RT Using the Redlich/Kwong EOT P (V-8) + show that the change in specific entropy of a gas between two states where the temperature is the same, T₁ T₂, and the pressures are P, and P2, respectively is AS - RIn( + and develop an expression for the change in internal energy. [V₂V₁+b) [V₂ (₂+b)

A tub that contains 1 kg of gasoline at 29 oC received 100 kJ of heat. Calculate the extensive entropy change of the system (tub of gasoline). Report your answer in units of kJ/K using three decimal places. You may assume the process is isobaric, and CP of gasoline is 2.22 kJ/(kg · K)

A piston/cylinder arrangement contains 2 kg of ammonia at a temperature 132.45 ℃ and a pressure 5 MPa. The piston floats. Heat is added to the system until the temperature of ammonia reaches 416.37 ℃. Is this process reversible in principle? Just answer with one or two sentences, without doing any computations. Determine the change of entropy for ammonia during the process. Use both the tables and correlations. Do you expect a positive or a negative change in entropy? Please, explain [one sentence is enough].
