1. The problem statement, all variables and given/known data Two well-insulated rigid tanks of equal volume, tank A and tank B, are connected via a valve. Tank A is initially empty. Tank B has 2 kg of Argon at 350 K and 5000 kPa. The valve is opened and the Argon fills both tanks. State 2 is the final equilibrium state. The temperature and pressure of the room in which the tanks sit are 300 K and 100 kPa, respectively. Perform a closed system analysis. a. Determine the volume of tank B. b. Determine the final temperature. c. Determine the final pressure. d. Determine the entropy produced in the process. e. Determine the exergy (or availability) destroyed in the process. i. Using an exergy balance. ii. Using the entropy produced.f. Determine the total exergy in tank B initially. 2. Relevant equations Ideal Gas law: PV = ZmRTFirst Law of Thermo E2-E1 = Q - W + ∑m(h+v2/2+gz)Second Law of Thermo S2-S1=int(1/Tb,1,2,dQ)+σ 3. The attempt at a solution PART A) using tabulated values for Tc and Pc of Argon, I found Z (compressibility factor) to be 0.9945~1, so I'm treating the Argon as behaving like an ideal gas. given TB1 and PB1, specific volume is found to be vB1=0.00137 m3/kg VB = vB1*mB1 VB = 0.02914 m3 PART B) My approach to find the temperatures would be to use conservation of internal energy between initial and final states. U1 = U2 U1 = UA1 + UB1 U1 = uA1*mA1 + uB1*mA1 where tank A is initially evacuated, so mA1 = 0, therefor U1 = uB1*mB1 and then for U2 U2 = uA2*mA2 + uB2*mB2 assuming from conservation of mass: mB1 = mA2 + mB2 and that since PA2=PB2 and TA2 = TB2, mA2 = mB2 = mB1/2U2 = (mB1/2)*(uA2 + uB2) assuming uA2 = uB2 = .5*u2U2 = (mB1/2)*(u2) U2 = .5*mB1*u2 now equating U1 and U2: uB1*mB1 = .5*mB1*u2 uB1 = .5*U2 = uB2 = uA2 so since I have uB1, TB1 and have equated the final specific internal energies to uB1, I can find the final temperature and move on. Yes? PART C) In order to find the pressure I would equate the specific volume of the tanks, resulting in .5*vB1 = vB2 = vA2 next using final specific volume and final temperature to determine the final pressure. Is this heading in the right direction?
