← ScienceWhich consequence results when pressure approximations violate Bernoulli's equation in rocket nozzles?
A)Detonation transitions to deflagration
B)Thrust significantly reduces at altitude
C)Boundary layer separation increases drag✓
D)Nozzle suffers catastrophic thermal failure
💡 Explanation
Boundary layer separation happens because an adverse pressure gradient arises violating idealized inviscid assumptions of Bernoulli's equation; this induces flow reversal and separation, therefore increasing drag significantly, rather than other failure modes which can appear under nominal condition.
