1. A steady-flow compressor is used to compress helium from 15 psia and 70°F at the inlet to 200 psia and 6008F at the outlet. The outlet area and velocity are 0.01 ft² and 100 ft/s, respectively, and the inlet velocity is 50 ft/s. Determine the mass flow rate and the inlet area.

2. A 2-m³ rigid tank initially contains air whose density is 1.18 kg/m³ . The tank is connected to a high-pressure supply line through a valve. The valve is opened, and air is allowed to enter the tank until the density in the tank rises to 5.30 kg/m³. Determine the mass of air that has entered the tank.
