Exhaust gases entering a convergent nozzle have a total pressure (Pt) of 200 kPa and total temperature (Tt) of 800 K. The gases exit the nozzle into ambient air at a static pressure (Po) of 101.3 kPa. Assuming that y 1.33 and R-287 J/(kg. K), determine the critical pressure ratio.

critical pressure ratio = 108.07 k pa

Explanation:

Pt = 200 k Pa

Tt = 800 k

Po = 101.3 k Pa

y = 1.33

R = 287 J/(kg.k)

critical pressure ratio ( Pc )

=  ------- equation 1

Pt given as 200 k Pa

Y = 1.33

back to equation 1

=

Pc = 200 * 0.5404 = 108.07 k pa
