1. Determine the irreversibility of a 4.00 × 10-3 kg, 80.0°C lead bullet traveling at 900. m/s that impacts a perfectly rigid surface aergonically and adiabatically. The specific heat of lead at the mean temperature of the bullet is 167 J/kg·K, and the local environment is at 0.101 MPa and 20.0°C.
2. A small room has a single 60.0 W lightbulb hanging from the ceiling. The walls are not insulated, so a steady state condition is reached where the room walls are at 55.0°F. Determine the irreversibility rate within the room if the local environment is at 14.7 psia and 40.0°F.
