Problem 5. Air flows steadily and adiabatically from a large tank at a stagnation pressure of P01 = 10 bar and stagnation temperature of To = 400 K through a frictionless converging nozzle and into a constant-area pipe with a diameter of D = 0.10 m and an average friction factor of f = 0.30. At Section (1) at the nozzle exit (or duct inlet), the absolute pressure is p₁ = 8.0 bar. At Section (2) at the duct exit, the absolute pressure is P1 = 5.0 bar. (a) Determine the Mach numbers and temperatures at Section (1) and Section (2). (b) Determine the length of pipe from Section (1) to Section (2). (c) Sketch the T-s diagram for flow from large tank to Section (2). (d) Briefly discuss what will happen if the length of the pipe is increased with fixed p01 and To.
