1. An initially evacuated 1.50 ft3 tank is to be isothermally filled with air to 50.0 psia and 70.0°F. It is to be filled from a very large constant pressure source at 100. psia and 70.0°F. The tank is connected to the source by a single 0.125-inch inside diameter tube. How long will it take to fill the tank?
2. An initially evacuated 0.500 m3 tank is to be isothermally filled with air to 1.00 MPa and 20.0°C. It is to be filled from a very large constant pressure source at 2.50 MPa and 20.0°F. The tank is connected to the source by a single 1.00 × 10-3 m inside diameter tube. How long will it take to fill the tank?
