Technical Notepad – RNX-57 Ideal Performance Calculations
RNX-57 @ 1000 psi chamber pressure
From results, for 100 gram mixture:
In the table above, iron (Fe) is included even though the quantity is negligible. This is to allow direct comparison with RNX-71V.
The specific heat at constant pressure for gas products (Cp) and for condensed-phase products (Cs) are shown in the table below. From these, the specific heats are calculated for gas-only products and for the gas/condensed-phase mixture.
The table below provides a summary of the thermochemical properties and ideal performance characteristics:
Note: calculation details for all thermochemical properties and performance parameters shown above are found in the Theory, 2-phase Flow web page.
