Unformatted text preview: c) Now assume that the tank is not rigid, but expands quasi-statically a small amount as the pressure is increased such that dp/dv = 1e05 MPa*kg/m 3 . If the helium reaches the same final temperature before igniting the 4 th stage (400K), what is the final pressure? d) How much work was done during the heating process in part c)? e) Sketch processes a) and c) on a p-v diagram. To make the sketch clearer you may want to accentuate the changes in volume with pressure for the second process. Also, include a series of isotherms in the background as a reference. (LO#4, LO#5)...
