Problem 5. Air flows steadily and adiabatically from a large tank at a stagnation pressure of P01 = 10 bar andstagnation temperature of To = 400 K through a frictionless converging nozzle and into a constant-area pipewith a diameter of D = 0.10 m and an average friction factor of f = 0.30. At Section (1) at the nozzle exit (orduct inlet), the absolute pressure is p₁ = 8.0 bar. At Section (2) at the duct exit, the absolute pressure isP1 = 5.0 bar. (a) Determine the Mach numbers and temperatures at Section (1) and Section (2). (b) Determinethe length of pipe from Section (1) to Section (2).
