A piston -cylinder device with a set of stops contains 10 kg of refrigerant -134a. Initially, 8 kg of the refrigerant is in the liquid form, and ttemperature is - 8⁰c. Now heat is transferred slowly to the refrigerant until the piston hits the stops, at which point the volume is 400 L . Determine (a) the temperature when the piston first hits the stops (b) the work done during this process. Show the process on T-v and P-v diagrams.

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?
