V12 V3 2) Consider the flow of combustion gases, through a normal turbine stage such that the flow angle at the exit of the rotor is the same as that entering the stator, and ai = as. The inlet total temperature is Tot. The axial velocity is constant V.. The flow leaves the stator at angle a2. The blade velocity is U. (a) Based on the velocity diagram in Figure 1, find the magnitude of V, in terms of V, and a, and the magnitude of V3 in terms of V, and as.
