Nitrogen flows through a converging-diverging nozzle designed to operate at a Mach number of 3.0. It it is subjected to an operating pressure ratio of 0.5:
a) Determine the Mach number at the exit.
b) What is the entropy change of the nozzle?
c) Compute the area ratio at the Shock location.
d) What value of the operating pressure ratio would be required to move the shock to the exit.
The 60-W fan of a central heating system is to circulate air through the ducts. The analysis of the flow shows that the fan needs to raise the pressure of air by 50 Pa to maintain flow. The fan is located in a horizontal flow section whose diameter i..
