burning rate การใช้

• The temperature sensitivity of burning rate is usually calculated from strand-burner test data.
• Here are some calorie-burning rates for a 150-pound person doing 30 minutes of housework:
• Its burning rate moderator and stabilizer for smokeless powder, and also a plasticizer for celluloid.
• Burning rate is inversely proportional to solvent concentration.
• The propellant consists of small cylindrical grains of smokeless powder with an extremely high burning rate.
• This simplified model neglects the change of temperature and thus the burning rate across the deflagration front.
• However, the powder burning rate changed as air pressure reduced, making them erratic for the new vertical shooting.
• The negative observations were low burning rates and that the thermal instability of peroxide was problematic for safety reasons.
• The fuse length was determined by time of flight, but the burning rate of the gunpowder was affected by altitude.
• Further modifications of its burning rate were achieved by shaping the powder grains into prismatic shapes, typically single-perforated hexagonal or octagonal prisms.
• Nevertheless, the strand burner experiment is easy to perform, can be repeated and a qualitative picture of the burning rate is obtained.
• The burning rate measured from a strand burner is typically 4 to 12 % less than actual burning rate observed in rockets.
• The burning rate measured from a strand burner is typically 4 to 12 % less than actual burning rate observed in rockets.
• By manipulation of the shape it is possible to influence the burning rate and hence the rate at which pressure builds during combustion.
• These wires are connected to a chronometer and the electrical signals are recorded at different time intervals so that burning rate can be measured.
• Organic peroxides do not generally release oxygen as part of the decomposition so there is little risk of enhanced burning rates due to oxygen enrichment.
• As the mass transport mechanisms that slow down the burning rates of traditional thermites are not so important at these scales, the reaction proceeds much more quickly.
• A : No . Chromium and ginseng are recommended by some salespeople and magazine articles, but research has shown that they have no effect on calorie-burning rate.
• In 1965, Keck joined the faculty of the Massachusetts Institute of Technology, where he began researching the problem of burning rates and pollutant formation in internal combustion engines.
• Both motors used a propellant burning rate and nozzle size appropriate for the full length design and were capable of about 1, 600, 000 kgf thrust for 114 seconds.
