2. Select typical failure rates find toverhaul for pumpset 1 or 2 when
system R(t)= 0.95 What is the motor pump set reliability at this
time?
3. First draw a reliability block diagram for one system delivering
water pressure and add the standbys after the model is developed.
The numbered components for Figs. 4.16-4.18 are
1. Electric drive pump
2. Valve
3. Electric power
4. Pressure flow regulators
5. Electric power standby
