Lesson 12.1: Turbine Example Problem

An adiabatic gas turbine expands air (ideal gas) at 1300 kPa and 527 C to 100 kPa and 127 C. Air steadily enters the turbine through a 0.2-m^2 opening with an average velocity of 40 m/s, and exhausts through a 1-m^2 opening. Determine,
a) the mass flow rate of air through the turbine,
b) the power produced by the turbine.
