Questions 2-(25 points) Consider the pumping system below. Fluid from the source tank is moved to the sink tank assuming that ac power would be needed to start and run the pump when the sink tank level is low. No other failures or human errors are important to consider. Assuming that the events of failing the ac power and pump failure can be represented by the following fault trees and the associated failure data shown, calculate the frequency of each scenario in the event tree and the total frequency of failure of the system. The mean values of failure probabilities and frequency of the initiating event(i.e., sink is low in fluid) are given in Table 2.1 below Pump fails o ac supply ac OR G+ AND Figure 2.1 A simple pumping system and corresponding fault trees of its subsystems Table 2.1 Failure Data for the Events Shown in Figure 21 Item 0.01 0 0.0 (a) Develop an event tree for the system considering the initiating event (D, and two subcomponents of ac, and (b) Assuming the imitating event occurs 10 times/month, please find system failure probability/the frequency Failure Probabilitv/Fr 5 per month pump.
