Introduction
The formula discussed in this section apply to setting fire scenario quantitative analysis, professionals without the need for complicated numerical calculation, it
Based on these equations can quickly determine whether the need to adjust the preliminary design of fire safety and how to adjust to meet the anticipated performance metrics to
begging. These formulas have been applied in the following areas.
--- Determination of fire plume convection, including convection and radiation;
--- Prediction ceiling jets in order to adjust the response time of the detector;
--- Calculate vent exhaust capacity;
--- Analysis of fire hazards and other flue gas transmission and flashover separated space.
For the smoke layer, the formula often used to estimate a time filled with smoke and the divided space required temperature and concentration of smoke layer.
For different types of smoke layer, this part of the Appendices B and C were given sample formula to calculate compliance with the requirements of this section.
Appendix B gives general information and conservation relationship smoke layer, Annex C gives the calculation of smoke layer characteristics specific formula and calculate
Examples.
GB/T 31593.1 provides for the use of mathematical formulas to calculate the general requirements fire dynamics, this section is with these general requirements
Body practices. If the consequences of the development of the mathematical model and the resulting fire use, the formula discussed in this section may be used for its
Conclusion verified.
This section for professionals engaged in fire safety engineering design personnel including fire, fire rescue personnel, fire standards
Makers, insurers, fire safety officers, standard user needs to fully understand the calculation method contained in this section are given in the relevant parameters
Meaning and application conditions.
