Question: A 400 L tank A contains argon gas at 250 kPa 30C Cylinder B
A 400-L tank, A contains argon gas at 250 kPa, 30C. Cylinder B, having a frictionless piston of such mass that a pressure of 150 kPa will float it, is initially empty. The valve is opened and argon flows into B and eventually reaches a uniform state of 150 kPa, 30C throughout. What is the work done by the argon?
Answer to relevant QuestionsAir at 200 kPa, 30C is contained in a cylinder/piston arrangement with initial volume 0.1 m3. The inside pressure balances ambient pressure of 100 kPa plus an externally imposed force that is proportional to V0.5. ...Consider the process described in Problem 3.49.
