Technical Notepad – RNX-57 Ideal Performance Calculations
RNX-57 @ 1000
psi chamber pressure
From Propep
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.
