r = ṁ_o/ṁ_f
This formula uses 3 Variables

Variables Used

Propellant Mixture Ratio - Propellant Mixture Ratio defines the ratio of oxidizer mass to fuel mass in a rocket engine's propellant mixture.
Oxidizer Mass Flow Rate - (Measured in Kilogram per Second) - The oxidizer mass flow rate in a rocket engine refers to the rate at which oxidizer (such as liquid oxygen) is consumed or expelled from the engine.
Fuel Mass Flow Rate - (Measured in Kilogram per Second) - Fuel Mass Flow Rate The fuel mass flow rate in a rocket engine refers to the rate at which fuel (such as liquid hydrogen, RP-1, or others) is consumed or expelled from the engine.

STEP 1: Convert Input(s) to Base Unit

Oxidizer Mass Flow Rate: 10 Kilogram per Second --> 10 Kilogram per Second No Conversion Required
Fuel Mass Flow Rate: 4.1 Kilogram per Second --> 4.1 Kilogram per Second No Conversion Required

Propellant Mass Flow Rate

Go Propellant Mass Flow Rate = (Nozzle Throat Area*Inlet Nozzle Pressure*Specific Heat Ratio)*sqrt((2/(Specific Heat Ratio+1))^((Specific Heat Ratio+1)/(Specific Heat Ratio-1)))/sqrt(Specific Heat Ratio*[R]*Temperature at Chamber)

Oxidizer Mass Flow Rate

Go Oxidizer Mass Flow Rate = (Propellant Mixture Ratio*Propellant Mass Flow Rate)/(Propellant Mixture Ratio+1)

Fuel Mass Flow rate

Go Fuel Mass Flow Rate = Propellant Mass Flow Rate/(Propellant Mixture Ratio+1)

Propellant Mixture Ratio

Go Propellant Mixture Ratio = Oxidizer Mass Flow Rate/Fuel Mass Flow Rate

Propellant Mixture Ratio Formula

Propellant Mixture Ratio = Oxidizer Mass Flow Rate/Fuel Mass Flow Rate
r = ṁ_o/ṁ_f

What is Propellant Mixture ?

The propellant mixture, in the context of rocket propulsion, refers to the combination of oxidizer and fuel used to generate thrust in a rocket engine. Propellant mixtures are carefully formulated to provide the necessary chemical reactions and energy release required for propulsion.
