5. (11 marks total) A well-insulated rigid container is subdivided by a partition into two parts A and B, each of volume VA=VB=0.2m3, and each filled with air. The initial temperatures and pressures are PA1=200kPa,TA1=100C,PB1=100kPa, and TB1=20C. The partition is then removed, and the system comes to equilibrium. (a) (7 marks) Determine the final temperature and pressure in the container. (b) (4 marks) Calculate the total entropy change for the air in the container in kJ/K. You may assume that air is a perfect gas with constant specific heats Equations and Other Data Work done in a polytropic process Pvn= constant, control mass: W12=(P2V2P1V1)/(1n) Work done in reversible steady flow: w=12vdP Entropy change for an ideal gas with constant specific heats: s2s1=cPln(T2/T1)Rln(P2/P1) Properties for air: R=0.287kJ/kgK;specificheatsat300K:cP0=1.004kJ/kgK,cV0=0.717kJ/kgK Universal gas constant: R=8.314kJ/kmolK
