Air at a temperature of 25° C and standard atmospheric
pressure of 101.3 kPa flows through the nozzle into the
pipe where the absolute internal pressure is 90 kPa.
The nozzle has a throat diameter of d = 25 mm. Gas
constant for air is R = 286.9 J/[kg K] and its specific
heat ratio is k = 1.40. (Figure 1)
