Calculate the volume of air and combustion products (vol.%) Generated during the combustion of 10 kg of the substance (Table. 2), if the combustion takes place under specified conditions (Table. 2) and the excess air coefficient (Table. 2). The volume of the combustion products result in the given conditions.
Option 3: The substance - 1-Butanol
Problem 4. Determine how many agents (tab. 5) may be burned indoors volume Vn, if you know that the burning stops when the oxygen content in the room is equal. To calculate the excess air ratio is recommended to use the formula (11).
Option 3: The substance - Methanol
Task 5. The method of successive approximations to calculate the adiabatic combustion temperature for the stoichiometric mixture with air of flammable material (tab. 6)
Option 3: The substance - Glycerin
Problem 7. Calculate what is the minimum amount of flammable liquid (tab. 8) must evaporate indoors vn volume under normal conditions, to create an explosive concentration of combustible vapors. Conventionally, assume that a pair of liquid fuel is uniformly distributed in the volume space. The lower flammability limit calculated from the calorific value limit.
Option 3: The substance - Toluene
Problem 9. Calculate the minimum phlegmatizing concentration of inert diluent, vol. %, Based on the minimum of the adiabatic combustion temperature of vapor of substance A at a dilution of its deterrent F (Table. 10), and the minimum oxygen content of the explosive and safe concentration of oxygen.
Option 3: The substance - acetate ester
Problem 11. Calculate a flash point or a flash point of a combustible liquid (tab. 12) according to the formula VI Blinov. Compare the value found with the experimental taken from the directory.
Option 3: The substance - Pentane
13. The task of a spherical charge of TNT (trinitrotoluene) weight W (tab. 14) explodes under standard atmospheric conditions. Find the parameters of the incident and reflected from the normal constraints of the blast wave from a distance R (tab. 14) from the center of the explosion.
Option 3: TNT Weight - 14 kg; Distance - 50 m
