Air in a large room has a temperature of 24° C and
absolute pressure of 101 kPa. It is drawn into the
200-mm-diameter duct isentropically such that the
absolute pressure at section 1 is 90 kPa. Duct has the
average friction factor of f = 0.002. Suppose that
L = 160 m. Gas constant for air is
R = 286.9 J/[kg · K] and its specific heat ratio is
k = 1.40. (Figure 1)
