WebThe later is accounted for with the mechanical efficiency. Confusingly, gas exchange losses and friction losses are sometimes combined into a single loss that is used to determine mechanical efficiency. This is discussed below. The remaining work, the brake work, is thus available from the engine to do useful work. WebIt is defined as the ratio of the initial energy stored in the resonator to the energy lost in one radianof the cycle of oscillation.[1] Q factor is alternatively defined as the ratio of a resonator's centre frequency to its bandwidthwhen subject to an oscillating driving force.
