A gas is being discharged isentropically from a tank of
pressure p1(abs) through a converging nozzle in a receiving chamber
of pressure p2 (abs) with critical flow condition in the nozzle
exit. If p2 is kept constant and p is doubled, the mass
rate of flow through the nozzle will

(a) not change

(b) be doubled

(c) be halved
