Consider 1 -D, steady, in viscid, compressible flow through a convergent nozzle . The total
temperature and total pressure are oT , oP respectively. The flow through the nozzle is choked with
a mass flow rate of om . If the total temperature is increased to oT 4, with total pressure remaining
unchanged, then the mass flow rate through the nozzle
Options:
(A) remains unchanged.
(B) becomes half of om .
(C) becomes twice of om .
(D) becomes four times of om .
