At one section in a constant-area duct the stagnation pressure is (66.8 mathrm{psia}) and the Mach number

Question:

At one section in a constant-area duct the stagnation pressure is $66.8 \mathrm{psia}$ and the Mach number is 0.80 . At another section the pressure is $60 \mathrm{psia}$ and the temperature is $120^{\circ} \mathrm{F}$.

(a) Compute the temperature at the first section and the Mach number at the second section if the fluid is air.

(b) Which way is the air flowing?

(c) What is the friction length $(f \Delta x / D)$ of the duct?
