Carbon dioxide (CO2) gas in a piston-cylinder assembly undergoes three processes in series that begin and end at the same state (a cycle).
Process 1-2: Expansion from State 1 where p1 = 10 bar, V1 = 1 m3 , to State 2 where V2 = 4 m3 . During the process, pressure and volume are related by pV1.5 = constant.
Process 2-3: Constant volume heating to State 3 where p3 = 10 bar.
Process 3-1: Constant pressure compression to State
Sketch the processes on p-V coordinates and evaluate the work for each process, in kJ. What is net work for the cycle, in kJ?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
