You may use resources beyond those associated with the class, but cite all of your sources.

Keep answers short and to the point. You will not get credit for being excessively verbose or providing too much information.

Consider a water pump system (used on a fire engine) that has two internal pumps driven by a single engine:

The pump has a single valve that is fed by two pumps. Water is sourced independently for the two pumps. Ideally both pumps should be operational. However, the system can work with only one pump. Both pumps are powered by a single engine.

1. Discuss the safety and human health implications of this device being engineered to perform reliably. (10 pts)

2. Describe this system using a tree chart and identify possible hazards for each of the system components. (10 pts)

3. Assume that component failures can only occur ateachpump (pump 1 or pump 2; so there can be a separate failure at each pump), the engine, and/or the valve (treat these as youronlyinitiator events, do not use any other initiator events). Construct a fault tree describing a failure of this system (no water released by the system). (10 pts)

Note.In an ideal situation, insights you would gain from problem 2 would influence what hazards you consider in the fault tree. However, for this particular assignment, please only use the initiator events we provide. This is done to ensure that you understand fault trees concepts and can apply them in a simple application. It also helps facilitate the grading of the assignment.

4. Identify all of the minimal cut sets associated with your fault tree. (10 pts)
