Do not use the 1st edition manual for the 3rd edition textbook. Problem numbers and data tables (like ( \gamma ) of JP-10 fuel) changed significantly.

Solving for pressure drops and combustion efficiency. 3. Rocket Propulsion

In a typical problem asking for thrust at a specific Mach number, the solution isn't just plugging into $F = \dotm(V_e - V_0)$. The deep solution involves calculating the nozzle exit pressure $P_e$. If $P_e \neq P_0$, you must add the pressure-area term $A_e(P_e - P_0)$ to your thrust equation. This is the most common "gotcha" in exam solutions.

The manual includes the for solving temperature ratios ( \tau_c ) and ( \tau_f ) simultaneously—something most students miss.
