This article derives a nomogram which enables the determination of jet fuels and their blends as a function of temperature. In the operation of flight vehicles, the temperature of jet fuel in the fuel system may vary from /sup -/50/sup 0/ to /sup +/120/sup 0/C, with a corresponding variation of viscosity by a factor greater than 10. At the higher viscosities of the cold fuel, the hydraulic losses in pumping and filtering the fuel are greater, and more settling time must be allowed to remove solid contaminants, water droplets, and ice crystals from the fuels. The lowering of viscosity when the fuel is heated may lead to leakage of fuel through clearances and seals, and in many cases to greater wear of the rubbing parts of pumps. The viscosity of USSR jet fuels is limited by standards, with a minimum viscosity specified at 20/sup 0/C and a maximum viscosity specified at /sup -/40/sup 0/C. Using the nomogram and knowing the fuel viscosity at any temperature, the viscosity can be determined at any other temperature.
