Abstract: This system's reliability, availability, maintainability and dependability were examined to determine which subsystem is most significant in this system. Structure of the model was explained with the system schematic diagram, transition tables and the system's states. The mnemonic rule was used to develop the first order linear ordinary differential equations associated for each subsystem, and all subsystems' failure and repair rates were shown to be distributed independent of one another and exponentially. Tables and figures present the numerical information for reliability, availability, maintainability, dependability and the impact of component repair rates on system maintainability. The evaluation of the subsystems demonstrates that the water vent control component is more readily available than the other components of the system. A rise in the time variable l and repair rate values, the system's maintainability would increase. Additionally, as each subsystem's repair rate values decline, the system's maintainability also declines.

Keywords: centrifugal; performance measure; maintainability; water intake; subsystem; availability.
