MATHEMATICAL MODEL FOR DETERMINING THE STEP TIME AND DISTANCE COVERED BY THE DROPLETS OF LUQUID FIRE-FIGHTING AGENT DURING THE PROCESS OF FIRE EXTINGUISHING IN THE CLOSED ROOM
The article deals with the mathematical model for determining the step time and distance covered by the droplet of liquid till the moment of contact with the horizontal plane. Numerical values of the step time and distance covered till the moment of contact with the horizontal plane are obtained. Experimental studies aimed on determining the effective diameter of the droplet are performed. According to effective diameter value an effective mass of the droplet is determined. After obtaining the effective mass value the step time and distance covered by the droplet of liquid till the moment of contact with the horizontal plane are calculated using a mathematical model.
