5. A 0.75m3 rigid storage tank initially contains 0.3kg of steam at 1 bar. The tank undergoes a two-step process in order to release some of its contents: (I) With the tank's release valve closed, a heat source at 950C adds heat to increase the steam pressure to 2.35 bar. (II) With the tank's release valve open, steam slowly exits until the final steam pressure goes back to 1 bar. In the release, assume there are negligible internal gradients and no heat transfer to the surroundings. Using the steam tables in Appendix A.III, determine the: (a) The amount of heat added in step (I). (b) The mass of steam released in step (II). (c) The total entropy generated by the entire process
