1. Obtain mass flow rate of oxidizer (_ moxðtÞ) with the known settling chamber pressure (Ps), settling chamber temperature (Ts) and throat area(Ats) using Eqs. (1)–(3).
2. As sume a value of η and ϕ.
3. Calculate _ mf ðtÞ knowing ϕ and _ moxðtÞ.
4. With the known value of ϕ calculate the C⋆theo from the equations given in Fig. 6.
