Two very large tanks, maintained at 323 k and 1 atm total system pressure, are connected by 0.1 m diameter circular duct, which is 5 min length. tank no. 1 contains a uniform gas mixture of 60 mol% acetone and 40 mol % air, whereas tank no. 2 contains a uniform gas mixture of 10 mol% acetone and 90 mol% air. determine the initial rate of acetone transfer between the two tanks. list the reason(s) why this process is considered "pseudo steady state"

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
