The stagnation chamber of a wind tunnel is connected to a high-pressure airbottle farm which is outside the laboratory building. The two are connectedby a long pipe of 4-in inside diameter. If the static pressure ratio between thebottle farm and the stagnation chamber is 10, and the bottle-farm staticpressure is 100 atm, how long can the pipe be without choking? Assumeadiabatic, subsonic, one-dimensional flow
