now opened, allowing some of helium to escape. The valve is closed when one-half of the 3. An insulated u.15-m' rigid tank contains helium (ideal gas) at 3 MPa and 130 "C. A valve is initial mass has escaped. If the exiting helium properties are assumed constant at the average temperature, determine (Assume constant specific heats): (a) the mass of helium escaped from the tank. 4 points) (b) the final temperature and pressure in the tank. (5 points) (c) the entropy change during this process. (6 points) Solution: He 0.15 m² 3 MPa 130°C now opened, allowing some of helium to escape. The valve is closed when one-half of the 3.
