Question

Consider the purely subsonic flow in a convergent-divergent duct. The inlet, throat, and exit area are 0.90 m^2, 0.60 m^2, and 0.75 m^2, respectively. If the inlet Mach number and pressure are 0.4 and 7000 N/m^2, respectively, calculate M and p at the exit.

Consider the isentropic flow through a convergent-divergent nozzle with an exit-to-throat area ratio of 2. The reservoir pressure and temperature are 1 atm and 288 K, respectively. Calculate the Mach number, pressure, and temperature at both the throat and the exit for the cases where (a) the flow is supersonic at the exit and (b) the flow is subsonic throughout the entire nozzle except at the throat, where M = 1.

An air flow at 90 psia, $1100 \mathrm{R}, M=0.3$ flows into a convergent-divergent nozzle with $M=1$ at the throat. Assume a reversible flow with an exit area twice the throat area and find the exit pressure and temperature for subsonic exit flow to exist.

A convergent-divergent nozzle with an exit-to-throat area ratio of 1.616 has exit and reservoir pressures equal to 0.947 and 1.0 atm, respectively. Assuming isentropic flow through the nozzle, calculate the Mach number and pressure at the throat.

00:02 Since m is equals to 1, add thrott, a is equals to a star, a t is equals to a star.
00:12 So a .e upon a t will be ae upon a star and which is equals to 2.
00:20 Now from the table the supersonic entry correspond to ae upon a star is equal to 2.
00:27 So here p o upon p e the value is equivalent to 1 .604 where reservoir pressure is p o and reservoir temperature is to so value of p e we get is 0 .93980m the value of p e likewise to o upon te the value is equal to 1 .018 so te we get is 282 .90k the value of te is this so here m .e is equal to m .e is equivalent to 0 .3.
01:08 So mt is equals to 1.
01:10 P ope is equals to 1 .83...
