Air is expanded from 1000 kPa and 600C at the inlet of a steady-flow turbine to 100 kPa and 200C at the outlet. The inlet area and velocity are 0.1 m² and 30 m/s, respectively, and the outlet velocity is 10 m/s. Determine the mass flow rate and outlet area. The gas constant of air is R = 0.287 kPam³/kgK.

The mass flow rate is kg/s.

The outlet area is m².
