8 is about 900 kg, or 2000 lb is going to be just under 1000 kilograms. There are various ways you can estimate this. Appendix II.Density and Viscosity of Water 0 C40 C Density, in Kinematic viscosity, Kinematic viscosity, Temperature, in Temperature, in Density, in grams pounds-mass per in square centimeters in square feet per degrees Celsius degrees Fahrenheit per cubic centimeter cubic foota per second second ×105 0 32 0.9998 62.42 0.0179 1. The scale is marked for 70 to 90, representing SGs of 0.70 to 0.90. Move the cursor to 0.80 on the Sp.G kgs scale. In this case, the answer is exactly 2000 lb. Therefore we are expecting an answer of about 2000 lb. What is the order of magnitude? Remember, we are dealing with 250 imp.gal. This scale is marked from 70 to 95, representing SGs of 0.70 to 0.95. One liter of water at room temperature (70F / 21C) weighs approximately 1 kilogram (35.2 ounces or 2.2lb). Without moving the inner scale, which is already set up as you require, move the cursor to 0.80 specific gravity on the Sp.G lbs scale. Dry Air and Water Vapor - Density and Specific Volume vs. There are four quarts in a gallon, two pints in a. Dry Bulb, Wet Bulb and Dew Point Temperatures Dry Bulb, Wet Bulb and Dew Point temperatures can be used to determine the state of humid air. Temperature - Imperial Units Density and specific volume of dry air and water vapor at temperatures ranging 225 to 900 degF (107 to 482 degC). 7 8 A US liquid gallon can contain about 3.785 kilograms or 8.34 pounds of water at 3.98 ☌ (39.16 ☏), and is about 16.7 less than the imperial gallon. Dry Air and Water Vapor - Density and Specific Volume vs. Let us do the ‘pounds weight’ conversion first. The US liquid gallon (frequently called simply 'gallon') is legally defined as 231 cubic inches, which is exactly 3.785411784 litres. Align 300 on the inner scale against the u.s. 75 SG is used, then 213 litres will be needed to cover the same distance.Īs always, set what you know. This energy may be expressed as range in nautical air miles, or possibly as endurance. You need a greater volume of fuel at a lower SG to give the same amount of energy as a smaller volume at a higher SG. The calorific value of fuel is related to its mass, not its volume.

For example, if a fuel has a specific gravity of 0.80, then one litre weighs 0.80 kg and one imp.gal weighs 8.0 pounds. Learn about the density of water, a measure of its weight per volume, and how it varies with temperature and substances dissolved in it. One litre of water weighs ONE kilogram in the metric system and one imperial gallon of water weighs TEN pounds in the imperial system.

Specific gravity (also known as ‘relative density’) is the density compared with the density of water. These indices have been spaced so that you can begin with an argument in one set of units and read off the answer in the other units.Ī little revision on specific gravity may be useful here. There is also a facility on the Navigation Computer to convert volume in litres or gallons to weight in kilograms or pounds if you know the specific gravity of the liquid (usually fuel).
