Jet fuel specific gravity calculator. Data on the density and specific weight of water across various temperatures and pressures. 2 The density if a jet fuel is 760 kg/m^3. For jet fuels, we extended the curve upward using the original equation without entering the transition zone. How do I calculate specific impulse? Fuel specific gravity is based on the ISA (International Standard Atmosphere) temperature at mean sea level, which means fuel weights will be approximate for temperatures other than 15 degrees Celsius. GTP API Gravity Calculator APP USD: (Registered Users Only) Availability: Available for download now Product Code: APP Click to Purchase from: Google Play Store App Store The API gravity calculator estimates the API gravity of petroleum liquids. FOR JET FUELS, WE EXTENDED THE CURVE UPWARD USING THE ORIGINAL EQUATION WITHOUT ENTERING THE TRANSITION ZONE. It is defined as the thrust produced per unit weight flow rate of propellant, and is expressed in seconds. 96469) whereas relative density is: Sep 2, 2025 · The Jet Fuel Weight Calculator is designed to help users quickly determine the weight of various types of jet fuel based on their volume. The volume of the fuel, however, is dependent on temperature, pressure and density (ρ) hence we cannot simply use a conversion coefficient. Specific impulse (Isp) is a measure of how efficiently a rocket or jet engine uses propellant to produce thrust. If you have the jet fuel density given in °API, use the API-to-gravity converter. Calculate minimum and maximum density values for jet fuels based on standard specs. The term “API gravity” refers to a scale developed by the American Petroleum Institute (API) to measure the density of petroleum liquids. Determine its density and specific gravity. API GRAVITY CALCULATOR GTP-3012-1A Corrects API hydrometer readings at any temperature (°F) to API degrees at 60°F. 1 The specific weight of a certain liquid is 90. . For additional information about jet fuel conversion, please refer to our resources. Jun 22, 2025 · Assignment 2. Oct 19, 2023 · An API gravity correction to 60°F calculator is a handy tool for the petroleum industry. 30 lb. The API gravity is a function of the relative density or specific gravity of the crude oil liquid. FOR AVGAS, WE EXTENDED THE GASOLINE CURVE DOWNWARD IN THE SAME MANNER. See also similar correlations for fuel oil, crude oil and lubricating oil . the fuel) to the density of water at a given temperature. This calculator will help you answer questions like, what is the API gravity of gasoline or petrol? Read on to understand more on the Specific gravity for liquids and solids is usually measured with respect to water at 4ºC (or 39. For avgas, we extended the gasoline curve downward in the same manner. e. API gravity is extensively used as a measure of the grade of crude oil products. 2ºF). Jet Fuel Properties Jet Fuel Min/Max Density Calculator Jet Fuel Nominal Density Calculator Kinematic Viscosity Surface Tension Vapor Pressure Multiple of Volume Distillation Curve The purpose of this GamGram is to review the entire subject of gravity, and also to explain the diferences between API Gravity, Specific Gravity, Relative Density, Density and Fuel Weight. Volume correction factors can be used to calculate the volume of a jet fuel at base temperature (15°C/59°F) if you know the density and volume at another temperature. Online calculator, figures and tables showing density, specific weight and thermal expansion coefficients of air at temperatures ranging -100 to 1600 °C (-140 to 2900 °F) at atmospheric and higher pressure - Imperial and SI Units. /ft^3. Specific Gravity - SG - is a dimensionless unit defined for liquids as "the ratio of the density of the substance to the density of water at a specified temperature". Density of water at 4ºC is 1000 kg/m 3 or 1 g/cm 3. Free Fuel Weight Calculator with four modes: jet fuel weight, automotive fuel weight, marine fuel weight and custom density. Convert fuel volume to weight in kilograms and pounds using typical fuel densities. Liquids - Specific Gravities Specific gravities for common fluids like acetone, alcohol, turpentine, oil and more. Instead we use the Specific Gravity, which is a measure of the relative density of one substance (i. This tool supports multiple fuel types. API GRAVITY & RELATIVE DENSITY CALCULATOR WITH THIS API GRAVITY CALCULATOR ERRORS CAN BE AVOIDED CREATED BY THE TRANSITION ZONE COMPARED TO THE PRINTED TABLES. Useful for engineering, fluid dynamics, and HVAC calculations. 2. A higher Isp means the engine extracts more thrust per kilogram of fuel consumed. Gases Specific gravity of gases is defined by: SG = Molecular Weight of Gas / Molecular Weight of Standard Air (Molecular weight of dry air is 28. API GRAVITY CALCULATOR With this API Gravity calculator errors can be avoided created by the transition zone compared to the printed tables. For gases the Specific Gravity is related to air. All of these measurements are simply ways to describe the weight of a fuel. cwgy tvchov iglc ggb abm hqqvydy tnqgm nqiags jctp cjhmh
