1. Determine the total availability of a 7.00 × 10-3 kg incompressible lead bullet traveling vertically at 1000. m/s at a height of 50 m above the ground. The temperature of the bullet is 150.°C and its specific heat is 0.167 kJ/kg ·K. The local environment is at 0.101 MPa and 20.0°C.

2. A stationary tethered balloon contains helium gas (an ideal gas here) at 0.00°C and 0.0700 MPa at a height of 1000. m. Determine the specific availability of the helium in the balloon relative to the ground, where the local environment is at p0 = 0.101 MPa and T0 = 20.0°C.
