How to Evaluate Oxidizer Mass Flow Rate?

Oxidizer Mass Flow Rate evaluator uses Oxidizer Mass Flow Rate = (Propellant Mixture Ratio*Propellant Mass Flow Rate)/(Propellant Mixture Ratio+1) to evaluate the Oxidizer Mass Flow Rate, Oxidizer Mass Flow Rate refers to the rate at which the oxidizer is consumed or expelled from the engine, it is used to determine the flow rate of oxidizer into the combustion chamber, which in turn affects combustion efficiency, chamber pressure, and thrust generation. Oxidizer Mass Flow Rate is denoted by ṁ_o symbol.

How to evaluate Oxidizer Mass Flow Rate using this online evaluator? To use this online evaluator for Oxidizer Mass Flow Rate, enter Propellant Mixture Ratio (r) & Propellant Mass Flow Rate (ṁ) and hit the calculate button.

FAQs on Oxidizer Mass Flow Rate

What is the formula to find Oxidizer Mass Flow Rate?
