Which consequence results when a converging-diverging nozzle's throat reaches Mach number one?

💡 Explanation

Flow becomes choked via the area-Mach number relation; the `choking` mechanism limits the mass flow because, at Mach 1, further reducing downstream pressure doesn't increase the throat velocity; therefore, further throughput is impossible, rather than permitting higher mass flow.
