Operating data are taken on an air turbine. For a particular run, P1 = 8 bar, T1 = 600 K, and P2 = 1.2 bar

Question: Operating data are taken on an air turbine. For a particular run, P1 = 8 bar, T1 = 600 K, and P2 = 1.2 bar. However, the recorded outlet temperature is only partially legible, it could be T2 = 318, 348, or 398 K. Which must it be? For the given conditions, assume air to be an ideal gas with constant CP = (7/2)R. …

Suppose that the laptop of Prob. 2.16 is placed in an insulating briefcase with a fully charged battery

Question: Suppose that the laptop of Prob. 2.16 is placed in an insulating briefcase with a fully charged battery, but it does not go into “sleep” mode, and the battery discharges as if the laptop were in use. If no heat leaves the briefcase, the heat capacity of the briefcase itself is negligible, and the …
