Nitrogen gas flows steadily through a pipe of diameter 10 cm. The inlet conditions are as follows: pressure 400 kPa, temperature 300 K and velocity 20 m/s. At the exit the pressure is 350 kPa (due to frictional losses). If the flow rate of mass and flow energy remain constant, determine
(a) The exit temperature
(b) Exit velocity. Use the IG (ideal gas) flow state daemon.
(c) What-if Scenario: What would the exit temperature be if kinetic energy were neglected?
