Unformatted text preview: tunnel is 10 psia. (a) Is the tunnel ²ow subsonic of supersonic ? Explain your answer. (b) What is the ²ow Mach number? (c) What is the total pressure of the ²ow in the tunnel? (d) For a reservoir temperature of 300K, assuming adiabatic ²ow, calculate the ²ow velocity in the tunnel. PROBLEM 3 (10 points) A * A 1 p 02 p 01 A normal shock forms inside a convergent-divergent nozzle. We want to develop a relation between the area ratio where the shock sits, A 1 /A * , and the total pressure ratio across the shock, p 2 /p 1 . (this relation cannot be expressed in one equation, but can be described by a set of equations). (a) Describe the procedure and equations you would use to obtain this relation. (b) Plot p 2 /p 1 versus A 1 /A * , with A 1 /A * ranging from 1.0 to 5.0. 1...
