A rocket engine has an exit nozzle area of 160 sq.ft., and is designed so that its nozzle causes the exhaust gases to expand
A rocket engine has an exit nozzle area of 160 sq.ft., and is designed so that its nozzle causes the exhaust gases to expand to the pressure of the standard atmosphere at \( 82,000 \mathrm{ft} \). The air at the combustion chamber is at zero velocity, \( 30 \mathrm{~atm} \), and 6,300 deg. F. The exhaust gases have \( \gamma=1.19 \) and a molecular weight of 19.8. What is the Mach number of the exhaust at the exit? Assume that flow through the nozzle is isentropic.
