Two streams of air mix in a constant-area mixing tube, the primary stream enters the mixing tube at station 1 with a velcoity of 300m/s and temperature of 900K. the secondary stream enters with velocity of 30m/s and temeperature of 300K. the flow at station 1 and 2 may be assumed one-dimonsion. Pressure at at station 1 is 0.1MPA. the ratio of primary to secondary flow areas at station 1 is 1:3.
a) Using contineuaty, momentum, and energy equations along with perfect gas law. Show how the flow at station 2 may be determined from conditions at station 1.
b) Find velocity, temperatue, and pressure at station 2. State all assumptions.
