Problem 3: Consider a series structure of 10 independent and identical components Each component has an MTTF 5000 hours. a) Determine MTTtm when the components have constant failure rates. (b) Assume next that the life lengths of the components are Weibull distributed with shape parameter a 0.2. Determine MTTFsystem and compare with (a). (c) Assume now that you have a parallel structure of two independent and identical components with MTTF 5000 hours. Repeat problem (a).

A system consists of five identical components connected in series
as shown:As soon as one components fails, the entire system will fail.
Suppose each component has a lifetime that is exponentially
distributed with ? = 0.01 and that components fail independently of one another.

3. Three components are connected to form a system as shown in the accompanying diagram. Because the compo- nents in the 2–3 subsystem are connected in parallel, that subsystem will function if at least one of the two individual components functions. For the entire system to function, component 1 must function and so must the 2–3 subsystem. 214 The experiment consists of determining the condition of each component [S (success) for a functioning compo- nent and F (failure) for a...

3. A liquid-liquid extraction process consists of two units, a mixer and a separator. One inlet stream to the mixer consists of two components, species-A and species-B. A stream of pure species-C is fed into the mixer to drive the extraction. The mixture is then fed to a separator where it is allowed to settle into two phases which are removed in separate streams. Each outlet stream contains all three species. The goal of the process is to produce an...
