Question
Ideal gas Oxygen (O2) flows through a well-insulated (adiabatic) nozzle.
The cross-section of the nozzle is circular and has a diameter of 15 cm at Station 1. Also, at Station 1 the flow has a pressure of 300 kPa, a temperature of 400 Kelvin, and a velocity of 20 m/sec. At Station 2, the temperature is 390 Kelvin. Friction can be neglected. Find the following:
