frequent failures in a thickener

  • Failure rate

    Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter (lambda) and is often used in reliability engineering The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system.
