Chapter 11, Problem 11.28(choose chapter or problem)
Air flows in a constant-area, insulated duct. The air entersthe duct at 520 R, 50 psia, and Ma = 0.45. At a downstream location, the Mach number is one. Find:(a) The pressure and temperature at the downstream location(b) The change in specific entropy(c) The frictional force if the duct is circular and 1 ft in diameter
