Q_ext = (C_v*ω_o)/G_L
This formula uses 4 Variables

Variables Used

External Q-Factor - External Q-factor is a measure of the energy stored per cycle in a resonant circuit or device, relative to the energy lost per cycle due to all forms of dissipation.
Capacitance at Vane Tips - (Measured in Farad) - Capacitance at Vane Tips is defined as the ratio of the amount of electric charge stored on a conductor to a difference in electric potential at the vane tips.
Resonant Angular Frequency - (Measured in Radian per Second) - Resonant Angular Frequency is the frequency at which a resonant system vibrates with maximum amplitude when it is excited by an external force, expressed in radians per second.
Loaded Conductance - (Measured in Siemens) - Loaded Conductance is a measure of the ease with which a load, such as a circuit or a device, can conduct an electric current.

STEP 1: Convert Input(s) to Base Unit

Capacitance at Vane Tips: 2.5 Picofarad --> 2.5E-12 Farad (Check conversion here)
Resonant Angular Frequency: 55000000000 Radian per Second --> 55000000000 Radian per Second No Conversion Required
Loaded Conductance: 2.5E-05 Siemens --> 2.5E-05 Siemens No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_ext = (C_v*ω_o)/G_L --> (2.5E-12*55000000000)/2.5E-05

Evaluating ... ...

Q_ext = 5500

STEP 3: Convert Result to Output's Unit

5500 --> No Conversion Required

FINAL ANSWER

5500 <-- External Q-Factor
