Unformatted text preview: M 2 = 2 . 0. Assuming one-dimensional Fow in the pipe, answer the following: (a) What could be the cause of the reduction in Mach number? (b) Calculate the temperature ratio T 2 /T 1 . (c) Calculate the pressure ratio p 2 /p 1 . PROBLEM 4 (10 points) A* A=3A* A* A=3A* (b) (a) 500 kPa 500 kPa A normal shock sits in a test section with A/A * = 3 . 0. The reservoir pressure is p 1 =500 kPa. A very skinny Pitot probe (no blockage e²ects) is placed in two positions: (a) with the inlet just past the shock; (b) with the inlet just ahead of the shock. Assuming isentropic Fow except across shocks, ³nd: (a) The pressure that the Pitot probe measures when its inlet is past the shock. (b) The pressure that the Pitot probe measures when its inlet is ahead of the shock. 1...
