The density of LNG is roughly in the range 410 to 500 kg/m 3. The bear market in crude oil, which took prices from over $107 per barrel in June 2014 to below $45 in March 2015, caused the spread to drop to below 16 to 1. W You can divide pounds per cubic foot by 32.2 for a rough value in slugs. Related Topics . Natural Gas Density is the ratio of mass of gas to the volume of the confinement holding the gas. Before you begin, keep in mind what you're looking for as an answer in terms of units. Density is mass per unit volume. Note that even if pounds per cubic foot is often used as a measure of density in the U.S., pounds are really a measure of force, not mass. The tricky part with gases is that you are often given pressures and temperatures with no mention of volume. It is found in oil fields and natural gas fields, and in coal beds. Z, Copyright © 2020 Petropedia Inc. - The density of gases have been listed below in alphabetical order in the units of both metric and imperial. Density of natural gas: There is no one correct starting (sea-level) density of natural gas since natural gas densities vary depending on where the gas was obtained. The natural gas is non ideal and thus, it follows a real gas law. J If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords.
