DETERMINATION OF DENSITY OF RP-1, T-6 AND RG-1 FUELS IN LRE WORKING RANGES OF TEMPERATURES AND PRESSURES
With aim to increase accuracy of determination of density of RP-1, T-6 and RG-1 fuels in LRE working ranges on temperature from -40 to 180ºC and on pressures from 1 to 1000 kgf/cm2 it is proposed two types of universal equivalent ratios ρf = f(T, p), in which individuality of each fuel is taken into account by set of coefficients derived from base of approximation of available tabular data and analysis of changes in (∂ρf/∂T)p and (∂ρf/∂p)T derivatives depending on temperature and pressure.
Keywords: LRE, fuel, density, temperature, pressure.
