Problem 2. 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. Please see the attached figure. Find the following:

The density at Station 1: ρ₁ ______________________________ kg/m³, and the mass flow through the nozzle: ṁ = ________________________kg/sec.

2. Enthalpy change between Stations 1 and 2: (h2 - h1)= _________________ J/kg

3. Velocity at Station 2: _{V2_______________________ m/sec}
