A passenger car collides with a gasoline tanker whilst travelling on a busy city central venue. The tanker has a total capacity of 50 m³, and at the time of accident was half full. As a result of accident, all the content flow out creating a pool of 4 cm depth and 1 m diameter, which immediately ignited causing pool fire. a. Develop 95% and 50% fatality risk contour [5 points]. b. Develop 95% and 50% injury risk contour [5 points]. Relevant data are given below: I Traffic Density: ■ ■ ■ B ■ ■ ■ Population density: Density of gasoline: Heat of combustion: Soot surface emission factor: 0.05 car/m² 0.9 person/m² 875 kg/m³ 45 MJ/kg Soot surface emission factor: Wind velocity: 0 m/s Density of air: 1.21 kg/cum Relative humidity: 95% 20 kW/m² 20 kW/m² The probit equation for death due to fire is: Y = -14.9 +2.56 In(t14/3/104) The probit equation for burn due to fire is: Y = -37.23 +2.56 In(t14/3/104) I: Effective radiation density, W/m² t: duration of fire, s To convert probit equation to probability: Probability -0.50 1+ Y-5 0.50 [1+ Yrs (√5)] - 5 -ведите здесь текст для поиска 1 [Help: The risk contour will be a circle of given risk potential, where risk is defined as likelihood of a particular severity.
