In chemistry, the burn rate (or burning rate) is a measure of the linear combustion rate of a compound or substance such as a candle or a solid propellant. It is measured in length over time, such as millimeters per second or inches per second. Among the variables affecting burn rate are pressure and temperature.
The burning of a solid material may appear to lose weight if the mass of combustion gases (such as carbon dioxide and water vapor) are not taken into account. The original mass of flammable material and the mass of the oxygen consumed (typically from the surrounding air) equals the mass of the flame products (ash, water, carbon dioxide, and ...
Burn rate is the rate at which a company consumes its cash. [1] It is typically expressed in monthly terms and used for startups. E.g., "the company's burn rate is currently $65,000 per month." In this sense, the word "burn" is a synonymous term for negative cash flow. It is also a measure of how fast a company will use up its shareholder ...
The burn rate of a company is a measure of its negative cash flow in a set period of time, typically a month. Investors, especially venture capitalists, monitor this metric closely to gauge when ...
Zwolinski and Wilhoit defined, in 1972, "gross" and "net" values for heats of combustion. In the gross definition the products are the most stable compounds, e.g. H 2 O (l), Br 2 (l), I 2 (s) and H 2 SO 4 (l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2 O (g), Br 2 (g), I 2 (g ...
It was quickly discovered that the rate of burning could be varied by altering the surface area of the cordite. Narrow rods were used in small-arms and were relatively fast burning, while thicker rods would burn more slowly and were used for longer barrels, such as those used in artillery and naval guns.

There's $1 trillion that needs to be spent -- and spent fast. As Andrew Ross Sorkin pointed out in The New York Times, private equity firms have a lot of capital that needs to be invested. As much ...
The burn area refers to the surface exposed to the heat of the combustion chamber, and it is just as pivotal to the regression of the rocket as the regression rate itself, since the volume flow rate of fuel is usually given by the regression rate multiplied by the burn area. Depending on the complexity of the grain geometry, it can also be ...
