A 1 m3 tank contains air (use the IG model). (a) Plot how the total stored energy (E) and total stored energy (Φ) of air in the tank change as the pressure is increased from 10 kPa to 10 MPa with temperature held constant at 25oC. (Assume atmospheric conditions to be 100 kPa, 25oC). (b) Repeat the plot for the specific stored energy and specific stored energy. (c) Plot how the stored energy and stored energy of air in the tank change as the temperature is increased from -100oC to 1000oC with pressure held constant at 100 kPa. (d) Repeat the plot for the specific stored energy and specific stored energy.
