1. Determine the minimum throat diameter required for a nozzle to pass 0.250 lbm/s of air from a stagnation state of 100. psia at 70.0°F.

2. Atmospheric air (14.7 psia, 70.0°F) leaks into an initially evacuated 2.00 ft3 tank through a tiny hole whose area is 1.00 × 10-6 ft2 . Determine the time required for the pressure in the tank to rise to 0.528 times the atmospheric pressure, if the air inside the tank is maintained at 70.0°F.
