Nitrogen flows steadily through a pipe with a constant cross-section area of 6cm^2. The nitrogen enters the pipe at 500 kPa and 50 degrees Celsius with a velocity of 15m/s. The nitrogen leaves the pipe at 200 kPa and 25 degrees Celsius. Assume that the nitrogen behaves like an ideal gas.
1) Determine the density, volume flow rate, and mass flow rate of the nitrogen at the inlet.
2) Determine the density and volume flow rate of nitrogen at the exit
