Air at a temperature of 25∘C∘C and standard atmospheric pressure of 101.3 kPakPa flows through the nozzle into the pipe where the absolute internal pressure is 85 kPakPa . The nozzle has a throat diameter of d� = 30 mmmm . Gas constant for air is R� = 286.9 J/[kg⋅K]J/[kg⋅K] and its specific heat ratio is k� = 1.40. (Figure 1)
