Venting is the most effective method of protecting structures from explosion severity. It provides overpressure protection from potential industrial explosion hazards by providing a planned pathway for the expanding gases to escape. Figure 1 shows the pressure-time variation in a 3 different vented gas explosion technique. a) Based on Figure 1, discuss thoroughly the flame development mechanism at each venting technique. [10 Marks] [CO1, PO1, C4] b) Explain the main problems in gas venting system and corrective actions that need to be taken to minimize the problem from getting worst.
