Problem 1xc) Stirling Expansion Stroke During the isothermal expansion stroke of the idealized Stirling cycle shown, the right hand piston remains fixed as the left hand piston travels downward. Problem 2xc The steam accumulator shown is used to maintain a ready source of new steam at 300°C. A piston of 63.6 metric tonnes maintains the required pressure, and the top of the cylinder is open to the atmosphere. 1 metric tonne = 1,000 kg The initial cold condition is shown at right. Heat is added to achieve the required end conditions The chamber contains no air. Find the temperature and steam quality when the piston begins to move Find the work done during the process and the final height of the piston at the desired condition of 300°C.

To provide some perspective on the dimensions of atomic defects, consider a metal specimen with a dislocation density of 105 mm–2. Suppose that all the dislocations in 1000 mm3 (1 cm3) were somehow removed and linked end to end. How far (in miles) would this chain extend? Now suppose that the density is increased to 109 mm–2 by cold working. What would be the chain length of dislocations in 1000 mm3 of material?
