The other properties are also functions of temperature. However, we'll use constant values equal to the average values over the temperature range obtained in the experiment. Enter the following constant values:

FLUENT uses gauge pressure internally in order to minimize round-off errors stemming from small differences of big numbers. Any time Anytime an absolute pressure is needed, it is generated by adding the so-called "operating pressure" to the gauge pressure:
  absolute pressure = gauge pressure + "operating pressure"

Enter -1112.3 for Gauge Pressure and click OkOK. (From experiment, measured outlet pressure is 97225.9 Pa. Corresponding gauge pressure = 97225.9 Pa - operating pressure = -1112.3 Pa)
